yep, thats about 20-25 quid GBP. But dont forget postage is on top. Not that you should moan for a bit of custom made equipment. All in all it worked out at about 48 quid delivered. Im sure it will be less if you went for slower postage maybe? i went for 4 day postage.
Still the only bits of kit i found that worked out the same sort of money where flimsy bits of metal.
Im more than happy with what i paid for it. Its a solid piece of kit, o and a rubber mount also came with it.
