In reply to afshin:
Holdz.co.uk are nice, and relatively cheap if you want something new.
I really like the look of the Agripp ones, but sadly anything via Beacon (usually an advert here -->) carries a £35 minimum shipping charge which is mental, think they're more geared up for supplying commercial walls.
Interestingly SoiLL holds are pretty cheap too, and very interesting designs too.
But, as posted above, Crusher and Beastmaker do some ace wooden holds which are more skin friendly, especially out the box.
Quite a few hold companies sell seconds too, though less useful if you want a symmetrical wall.
