Re: help with salt setup
As far as where to get flies-
Least expensive are discount online flies from places like Big Y, Bluefly Cafe. Although inexpensive they can be a bit dissapointing-- over dressed, out of proportion and not as durable. they typically run 1.30-1.50 a piece, with discounts on larger quantities.
Flies tied by Umpqua and Rainy's are available in a lot of large online stores and are decent and a a bit more expensive at 2.50-3.00 a pop for standards like Clousers and Deceivers with assortments discounted a bit. You might consider the striper/bluefish assortment as a good way to get started with the basics and top it off with a couple of other patterns from Raineys Umpqua or locally tied patterns from sources like local shops or shops that specialize in saltwater (below)
Locally tied patterns from places like BearsDen and saltwateredge typically run 5-6 bucks a pop, but are often well tied effective imitations not available elsewhere. They also typically stock Umpqua or Rainy's flies too at a bit of a markup for the basics.
Tying most of these patterns yourself is relatively easy, and for the most part use inexpensive materials-- once you get over the initial investment of vise, tools etc, and initial stock of hooks and starter materials it becomes pretty easy to crank out a variety of effective patterns out for well under under a buck a piece, but it will take a lot of tying of flies you would have bought anyway to make up the investment.
