Hmmm... You know, my wife knows how to get on here now... [:-]
Oh gosh, let's see...
That's two seperate 4x8' sheets of woodgrain pegboard from Lowes. I think they sell for around $35 a sheet or so.
The top is one sheet of cabinet-grade plywood that was birch, I think. I was going to buy oak from Lowes, but it only came in 1/2", and this was pre-finished and 3/8" thick. I like the idea of pre-finished, however, if I had it to do over again I would go with the 1/2". At the time, I was scared that it would be too heavy... But when I finished building my framework underneath, I realized I could park a truck up there and it would probably support it.

The laminated plywood's close to $50.
There's probably about five 2x4's, varying from eight to 10 feet in length, $3-4 apiece or so.
I've got about $50 in little brackets underneath which can again be purchased at Lowes; these made it super easy to attach everything, as I didn't have to "toe-in" any nails or screws or anything. The whole thing is screwed together, and that's probably another $25 or so just in screws... Yep, can you say "over-engineered"? [8D]
Of course, then you've got the Coffey scale, $50...cutoff saw, $100...Apple vise, $75, Bowmender press, $75... Digital grain scale, $40... Easy-Eye Laser, $90... The couple thousand in bows... Never mind. I'm stopping while I'm ahead.
At least I never have to go to another Pro Shop to have work done now... in fact, my workshop is nicer than almost every single shop I've been to so far in a two-hour radius; it's a super blessing to have such a place to be able to tinker in, and I'm extremely thankful.
