( I wasn't sure where to stick this - toys, gifts, gear, etc so I chose home since that's where it'll be )

My husband walks over to me tonight while I was washing dishes and casually mentions that I need to figure out what kind of swing set we want for our backyard. This was really left field but apparently the grandparents and great grandparents want to buy a swing set for the kids and we need to figure out what kind we want, what configuration, what kind of materials, etc.

I admit I know absolutely nothing about swing sets and my two are pretty little (nearly 2 and 3 respectively). Any thoughts, ideas, etc? Or anyone want to offer some eye candy? Mr. Bear wants it to be mostly wooden.
