Hey SLIMER, I was once told to start from little up.. I saw the other day at GANDER MOUNTAIN a starting kit for under $50. You get the basic Vise, Thread, feathers and soo much other little things, you prob wont even use..
I would suggest to start there and then after awhile you would then know where you want to be. The many different vises you will see out there are all made up by others before us who have crafted their own to fit their needs and thought it would benefit those after them. The Vises do vary in Prices from $25 ( As LOSTLURE stated ) to $500 + vises. I have started just a few months ago with the Starter kit and its been doing me great.
Heres alittle Article if you have time to read.
Hope this helps
If you need Hooks to Practice on, just let me know.. I have Hooks I dont think I will ever use..
