don't scrimp, you don't need a crash tested one but you do need one from a reliable fabricator. there are some shockers on ebay. lets face it, i could template my one, cut some pipes and weld one up, and i can't weld!
canons forge are generally regarded as good. personally i like (and have) the spacesaver from jds metaltech. i would buy another without hesitation.
a world of waves and a world of ways to ride them!
