Elliptical Cross Trainers

I am looking into getting an Elliptical Cross Trainer for the house so that I can exercise. I don't like not being able to go walking or running in my neighborhood and I really don't have that much time to do so either. With all the running around I have to do I don't even have time to exercise with my "The Firm" workout videos. Life is just so busy that it's hard sometimes to keep up with what is new in my life. Well I have been really wanting an Elliptical and have been looking online for that right deal. Now here's what I am really needing. I am needing something that will be able to fit into my living room and or spare bedroom so that I can store it somewhere. I know that it will get use out of it because that is the only thing that I use at a gym anyways. It's nice to be able to do that and it doesn't hurt my knees and ankles either because it's not hard core impact on them. You still will get a pretty good workout on them. Oh the choices I have now to look at. I was going to use my money that I am getting for blogging on christmas but instead I might use it to get a new elliptical machine. I deserve something nice for a change and this would come in very handy for me and with the winter coming. So if any of you know where I can get a nice used one or even a new one for a good price let me know. The space saver ones I am really liking but they are so expensive. Just let me know. :)
