There's a thread in the DIY somewhere on making your own. I have 2 sets of them and have never had any issues with them coming off/rolling around etc. I think they wound up costing me around $25 a set. I've used them for heavily for 7 years and I would guess I'll get another 5-10 years of heavy on them. I've worn out 2 sets of fins in that time.
