Here's mine that I just got done a couple of weeks ago........this is all from scratch in my basement on unfinished walls. $385 in materials and finishing. 8X10' 40" high ,24" deep. (All 2X4",2X6" and a $50 piece of oak plywood.)
I wired in 5 outlets, a ceiling fan and two 4 ft. Flo. Shop lights.

I also have an 11 yd test shooting / tuning range , bowrack, complete fly tying area for my fly fishing habit, and a workout area all out of sight.
XM satellite radio and portable DVD for entertainment.

Cable gets run and I pick up my "Puffy" chair this week.

I love my basement.
