I would say that if anything it would be therapeutic for you. Plus you get to have a good Cardio workout too!!
Up keep would be minimal but as far as a refurbish I have only met one that was too bad for me and it sat under water for a few months and there was no way I could get it unstuck. I usually can get a locked up machine working no problem but that one had my number!
I say go for it!!!
