Boy, are we ever in the same boat. I have B/G twins turning 2 at the 1st of Dec., so I have been researching the Rainbow Play Systems. I'm not really sure where you are located, but we are in Frisco and I have been talking to USA Baby (in Frisco). There are three different Series that you can choose from, the Castle and the Clubhouse are the more expensive ones, then the Carnival Series is a little more affordable. The only difference between them is the C/C are made with 4X6 wood and the Carnival is made with 4X4 wood. Everything else is the same. There are catalogs that you can get and pick out the one that fits you best. You need to look really hard at them because I found little things that I didn't like on some of them which really help narrow it down. I finally came to two of them, one which would run me $3600 with delivery and install, and the other $2800 with the same. The difference, mostly having wood roof, or canopy. I have another baby that is 4 months, so I had to look to the future to make sure there would be enough room for her too, so you may not need three swings. All of our neighbors have the Rainbow systems and love them. Sorry about the length of this, but I was in the same boat about 4 mths. ago. Apparently they can install within a week, but ask and make sure nothing has changed. Good luck!!
