It could be worth checking the For Sale/Wanted on UKBouldering.com as well as here, e.g. :

If that one's gone, it's pretty common to see wooden hangboards for sale secondhand, often by people who've bought a Beastmaker 2000 and want to sell it and get a 1000 instead, or vice versa. So yeah, they're absolutely about.
Or you could look at
http://crusherholds.co.uk/portable-fingerboards-hangboards -- a pair of the little hanging boards might meet your needs, and are relatively cheap.
> or if it is even the right thing to do
Do you mean "right thing" ethically (are you worried about depriving the hangboard-makers of money?), or whether it's suited to your training needs?
