We bought ours for like $300-400 from Walmart. It came in big boxes and it took Wayne & one of his friends a day to do most of it. Then my dad came over the next day and helped Wayne for a couple hours finish it up. I dont think it was very hard for them to put together, just took up some time.
Im laughing because we just set ours up on the grass.

We didnt prep the ground or put down mulch or anything. The set seems fine...
We had looked at the really expensive ones at a playset store, but we werent sure how long we'd be in this house and didnt know if we wanted to make that kind of investment. Now we're staying here, but we figured at $300-400 we can replace it easily with a new one in a few years. Esp. with us getting hurricanes and stuff. kwim?
Here are some pics of ours after we put it up. This was when Kaili was like 2 1/2 though. LOL!
