Thanks for the input guys. Howie - thanks but I'm Scottish and haven't found one for less than the equivalent of $65 over here. Not a huge amount, but I really don't have any spare cash. Good name btw :).
I think I should be able to make one that can hold up, as the heaviest I'll use it for is a 88lb kettlebell one-arm press at a bodyweight of 220lb. So it's not like it'll be withstanding massive weights.
