DH and I are thinking about getting DS5 and DS(almost)3 a bounce house for Christmas this year. I've looked on ebay and they seem to be reasonable. I'd had in my head about $200 which seems about right. Anything I should look for while I'm trying to figure out what to buy?? I know the kids would get my money's worth out of it and the price of buying one is just about the same as the cost to use it once for a party. I just have no idea what I'm looking for or if $200 is still way too high. I would so appreciate any advice in this area!
