+1 on build your own. Awesome game.... The best for tailgates as well and it's an easy project... Took about an hour to build a set plus the time to paint/clear them. If you do any woodworking at all, you likely have all the tools required except probably a 6" hole saw which you can get for 10 bucks.
I bought a 1/2" full sheet of sanded birch plywood from HD for about 40 bucks and had them just cut it into 4 equal 2'x4' pieces while I was there, which will build you 2 sets. Add about 15 bucks in 2x4s and 10 bucks in hardware per set. I also opted to use some paint I already had and then clear them with spar urethane to finish mine so they are waterproof and uv resistant. Amount of slide is near perfect with the spar urethane in satin. All-in cost for me to build 2 sets, with very nice bags, came out to about 80 bucks per set. One to keep and a really nice gift for someone.
