I have 2 Hi-Lift jacks and lots of accessories for them, sand plate, winch adaptor, pipe lift adaptor, fence stretching adaptor, wheel lift adaptor, log splitter, bar clamp adaptors, vice clamp adaptors, the list is endless.
I'd recommend buying the actual Hi-Lift model, they're rebuildable for under $20 and dont fail like I've seen lots of the cheaper knock off's do.
