Just checked on their web site, for those interested.
A complete Steel Challenge set, all 8 stages is $3,500. Just steel and hangers. 40 metal bases adds $2,000.
A practice set (4x10, 5x12, 4xrectangles) is $1,000. 5 metal bases would add $650.
I've got 1x10 and 1x12 and have just ordered 1x10 and 3 hangers. Comes out to $105, free shipping.
I think I'll do the $100/mo till I get all 9 rounds w/ 5 hangers.
Got to add you own 2x4 posts and for competition of course the 11 shooting boxes.
