I bought a set on ebay, mounted them and was so impressed I bought 2 more sets!!!!
the ones I got are aluminium (yes people, this is the right way to spell it, just 'cos you guys got lazy and dropped an "I" doesn't make it right....), very low and I think discontinued, but it's a shame because for the money they seem excellent!
I assume that the steel and stainless steel ones they still sell are of comparable quality.
