These look pretty cool too:
http://www.hotgym.co.uk/Been contemplating buying one for a year, I think when we move in January I can convince the missus to let me get one finally :p
I figure you can hang rock rings off of it too, I use mine now and again (rock rings), they're ok not as good as a fingerboard but definitely better than nothing also these things are pretty cool:

I have been using them in the gym quite a bit lately, loads of great exercises you can do on them, fantastic for shoulder stability, but the best thing is they weigh next to nothing and you can travel with them and set them up anywhere really easily with a door anchor.
If the door frame can handle my fat ass it'll probably be fine with yours
Disclaimer I am a crap climber/boulderer who has never done anything better than V4 or whatever the french grade equivalent is, i've only just started again recently after almost a year out for various reasons, so make of my opinion what ya will, although I did use to do a helluva lot of weightlifting and powerlifting for many years (although these days I take it less seriously) so my exercise knowledge base is arguably better than my climbing skills hehe.
