Definatly make your own. It's fun and if I can do it any body can.
Lots of how-to's on youtube.
The basic tools needed are something to cut the leather with (Duh), a groving tool, an awl, and a stitch spacing wheel.

You'll need some rubber cement, a drill (drill press is better) and belt sander for the edges ( you can hand sand em if you don't have one).
There's tons of info on the net.
PS,,, I use a utility knife to cut the leather. A small diamond stone will keep em sharp.
I"m far from an expert but if you deceide to try your hand at it PM me and I'll try to help.
