Have the same conversation with new fly tyers, why spend hundreds on top quality gear then assemble it with crap tools! Seriously guys, I get $400.00 every year to spend on hunting and that's it! If I get a $200.00 bow half the budget is gone, so I do everything on a very slim budget, but I still sprang for the Bitz. Love your Plastic knock off, lets stack fletchings side by side in 5 years, mine will still be even and uniform everytime, Yours? Well I've yet to see anything plastic maintain it's shape over time with repeated use. Not to mention that they are hard to keep clean don't hold the fletchings nearly as stable and are light and flimsy feeling to the hand. Like any other tool buy the best you can afford just don't forget to factor in the replacement cost of getting by with junk.
Flytieing vice = Renzetti
Fletching jig = Bitzenburger
