A couple suggestions for you. As I remember you’re in Texas and will chasing bass, panfish and maybe some SW stuff like reds and specs.
The tough thing about buying a vise is that there are a lot out there with different features and designs. It’s also a personal thing so what works well for one person may not for someone else, and to some extent some vise designs are better than others, and a there’s a big range in prices and quality.
So there are a couple ways you could go, but the best way is to see if the shop offers tying classes, or maybe there’s aFF club nearby that does. The Federation of Fly Fishers and Trout Unlimited have affiliated clubs/chapters all over the place, and they offer casting clinics, tying classes etc. and it’s a great way to jump start the learning curve. You can do a search here:

It would be great if you could take a class with a loaner vise maybe leaving a deposit so you can practice your “homework” and get some tying under your belt before you spring for a vise. That way you’ll have a better idea what to look for, and what works for you.
In addition to fixed jaws, there are two types of rotary vises:
360 rotary- allow you to view the fly from all sides and top and bottom
“True Rotary” or “In-line Rotary” same as above, but they also rotate the shank on a central axis so you can tie using rotary tying techniques- like spinning the jaws to wrap thread or other material around the shank. You can also tie conventionally with “true rotary” vises.
Since you’ll tying on some good size hooks for bass and saltwater, and applying some heavy thread torque on a lot of patterns (spinning deer hair for bass bugs), you’ll want a sturdy vise that won’t tip (c-clamp or heavy base), and good quality steel jaws that will hold large hooks rock solid. Whatever vises you look at, make sure they will hold the range of hook sizes you plan to tie on, allowing some margin for going up or down in sizes in the future.
Here’s a good article on different vise designs:

Here’s a 2006 review of vises:

As mentioned the best thing to do is try a couple different ones to see what seems to work best for you, but just as a starting point, for under 100, I’d look at:
HMH Silhouette – (for about 80) 360 rotary. The “Silhouette SX” not the regular “Silhouette” would be my choice if you were tying a whole bunch of different sized flies-really big stuff and really small in addition to your basic bass and basic redfish type saltwater patterns, it is comparable to the DynaKing Kingfisher in quality and price and has the feature of interchangeable jaws (Midge, Omni and SW) whereas the base model Silhouette doesn’t. But for you, the Omni jaws, standard on the regular, less expensive Silhouette, will hold hooks from small 20’s to 2/0 and would be a good choice.
Danvise (about 80) A good vise, and an exceptional value at the price for a “true rotary”. Although it has steel jaws, many other parts are made of Delrin (plastic composite) so it’s a love it or hate it thing with many tyers. A potential drawback is that you’d probably want to add an extension arm (20 bucks) for tying larger bass and SW patterns, but you wouldn't have to do that right away, only if you needed it. The jaws can be a bit fussy to adjust, but there’s an excellent DVD that explains how to do it, and they hold hooks up to 2/0. It comes as a c-clamp and finding a base for it can be a bit tricky since it’s not the standard 3/8”, it’s metric.
There are a lot of options for a bit more, but this one is also worth a look IMHO:
Peak True Rotary- (about 150) a “true rotary vise” that spins the hook shank on a central axis. It’s a great vise—the only caveat is that it comes with standard jaws that tie up to size 2 (not 2/0). That should be fine for bass, but for SW, you might also want to add the optional salt water jaws (about 35 bucks) at some point down the road to tie larger patterns (up to 6/0!!).
The prices listed above are suggested retail. But you can often find great deals in these tough times if you search around. (The 127 price, with free shipping, on the Peak is a great price.)
Again, try and get your hands on a few different ones. Since you've had some experience tying you won't be starting from zero, so you'll be able to get a sense of what design/features you like.
