Have you ever used a Rowing Machine?

I was thinking give or take a few buying one but I'm wondering how people close to using it in the long run. It's not other practical for me to get out to the gym, so I want something to use at home that will not nick up alot of space and stores easily. A rower seem the way to walk, but do you like the workout? Comments please...Have you ever used a Rowing Machine?
Yes, rowing machines are an excellent approach to exercise the whole body and it's more aerobic than most machines. Renting a row boat on a small lagoon or large pond is even more fun.
I use one at my university, I like it, it's alot of fun. Ths is coming om someone who hate exercise.
