Re: what would you buy??
here is some basic tools/ideas I recommend
2013 renzetti traveler $160
dr slick or equivalent scissors
ceramic insert/tube bobbin holder (steel tube bobbin holders are ok to start with and nobody can tell you/us how long it takes to wear the tip using thread)
bodkin (a dowel with a sewing needle stuck into it works just fine)
forgo the bobbin holder threader entirely and learn how to draw the thread up the tube using your mouth
hackle plier - get a decent one for smaller hackles. the natural hackle plier you have on your hand (finger & thumb) will work excellently with longer hackles
hair stacker - get one but if you don't foresee stacking hairs or buck tail in the near future, then buy this one later on
whip finisher - learn to do a hand whip finish and save yourself some money to buy materials
utility scissors - get some scissors like the fiskars with the orange or black finger holes and use these scissors in place of your expensive one to cut up materials, hairs, wire etc
YOUR way is not the ONLY way when tying flies!
Fly tyers can be masters of making things complicated!
You're only limited by lack of imagination. Be creative, experiment.
