you can see mine on my daycare websites, http://www.freewebs.com/tarastoyland and http://www.AtoZLearningTreePreschool.com - I must say it is the most envied playground on the block and among my daycare provider friends.
Our set is a Cedarworks. http://www.cedarworks.com We custom designed it and if you ask to see the Parkman set from Plainfield, IL they will be able to do our set exactly. LOL.
Since I do daycare I needed this set to be a long term purchase. I went with Cedarworks because the wood - Northern White Cedar - is the ONLY type of wood that will never splinter at all. We have had the set almost 5 yrs now and not a splinter yet. We have never treated it, stained it or done anything but make sure bolts are still tight and it's in perfect condition. I liked that they used true 4X4's - lots of other companies don't. I also liked their hardware, the safety features and the play value.
My kids are now 6 1/2 and almost 10 and they still play on it all the time. The daycare kids will spend ours out there every day playing if they can.
We looked at every other brand there was. I didn't like a few things about Rainbow - I got a huge splinter in the show room there, I bumped my head a few times on the demo sets due to poorly placed cross beams and I didn't like that they had rope ladders to no where and play items that just didn't make sense (climb up this thing and go to nowhere?). I liked how our set combined both sides with the tunnel up top.
