I help run a school climbing club and we could do with finding a cheap source of belay devices for the kids to buy. Some have recently been paying over the odds and/or getting poor advice buying climbing kit themselves.
Ideally we'd like some of the latest 'grooved' ones to give maximum holding power but don't want to be paying £15+. I haven't found any good deals that stand out so I thought I might ask for suggestions.
I don't want original VC Pros despite the fact you can get them for £7.50 as they lock up badly. The Outdoor Shop is/was selling ATCs for £10 which is great but they are one of the slickest devices which isn't ideal. DMM Bug cosmetic seconds are available from V12, again at £10 which could be an option.
Another option might be a bulk buy of 10 Rock & Run Graviton

Otherwise does anyone have any other suggestions?
