I was looking at this jockey wheel, but in the end decided to buy an ALKO on special from supercheap instead. Reasons not to buy were weight (it's a seriously heavy unit) and price - more than double the ALKO.
However, for some insane reason SCA don't sell U-bolts. Spectacularly dumb policy since they sell things that need u-bolts.
And then this morning I get an email from ebay saying the price on this has dropped down. $240 is a sharp price for this unit, on special it normally seems to be about $319 at most shops. I've got an automatic ebay plus code applied that brings it down to $168, which is spectacular - code BFRI30 .
According to the seller it also comes with the mounting fixtures (u-bolts) which makes it even better. I'm pretty sure I'll take the ALKO back to supercheap and just buy this, it's a superior product in every way except weight.
Really good price!
