In reply to geoff.comley:
I'd get quality ergonomic non-tweaky resin holds:
core/bleaustone/HRT/entreprises/Moon
mini jug/incuts/pinches/slopers/crimps
then fill the rest of the board with home made wooden ones. Try get a load of offcut wood off timber yards or friends..etc
Then ask local walls if they can sell you some t nuts and bolts (as you usually have to bulk buy these).
