Well I haven't had a lot of money to put into a home gym, so I go with what is affordable. I managed to pick up a stair stepper for $25 at a yard sale. It's a "Tri-Stepper". Gives a very good workout on the legs. I also have a $50 Strider from Wal*Mart. It's kinda like a 1 foot tall quasi elliptical. I have something similar to a Gazelle that my mom didn't use and passed on to me, and the rest is all small stuff like hand weights, videos, exercise ball, step for aerobics, hoola hoop, and leg weights.
One piece of outdoors equipment I did invest good money in...a jogging stroller. I have a little one myself (2 yo). You can get double joggers. Take the kids to the park and get in some running while they sit back and take in the scenery.
As for the treadmill. I'd love one. But for now, I'm content in the winter to simply run in a figure eight pattern from one corner of my livingroom to the other. LOL It works for me.
