Hi Alan,
look on fleebay……..so far I've found that the likes of Sealey operate a badge engineering formuler……
they buy the stuff in from the same people we can more or less but often double the price cos it's got their sticker on it….
No better built and from the same far eastern factory…….
I know this as a fact because the very large motorcycle lift I bought was exactley the same at a tad over 1/2 the price and with courier delivery thrown in……..
I do have a couple of supplers (for this kinda stuff) I use if you want the address's PM……..
As for the job you want to do please buy something a little bigger than u need, not for strength but for stability…it all get's top heavy real quick when things start to go wrong….
good luck Clogs………
