I just jumped head first down the bow tuning rabbit hole and learned a lot in the last few months. So much free content out there. 300 would almost get you an ez green press. I have a mathews vertix and have totally redone everything. The bow shops around me invest zero time in tuning a bow. I installed new strings, rest, nock sets, d loop, peep, cam timing, cam sync, top hats, 2nd axis, 3rd axis. Made a draw board, paper tuning stand, got an ez green press, made an arrow saw. Bought levels, scales, serving jig, fletching jig. Watched a ton of videos. Dudley, aron snyder, levi morgan and any video on tuning a mathews. Seems complicated at first but the more you learn the simpler it gets. Bows are expensive and should perform like they should. I've had fun with it. Buy the tools and start tuning. You won't regret it. Plenty of free material out there to get started. Archery talk is good reading but have to weed through a lot of BS.
