In reply to WaxiesDargle:
Depends on the height of the room, but I think you would probably get more out of a good hangboard.
My garage wall is 10ft wide and about 10ft high (angled at 30 degs) and it's only just big enough to do 'problems'. Crucially though, there is enough space in my garage to swing around and fall off without risk of hitting a wall.
A friend has a smaller wall and he is restricted to repeating small circuits with defined hand movements. But it's all about motivation - despite having a smaller wall, I think he uses his more than I use mine!
