Hi guys

Ive come across this product which I am probably going to buy. It looks like a damn good idea...if not a little expensive. Has anybody seen or used one of these before? It allows you to jack the boat off the trailer and then remove the trailer safely. The screw jacks will also allow for easy raising and lowering when adjusting bunks and rollers on the trailer.

I have started my project boat (I'll only post pics and details once I have finished, just in case I completely stuff it up) and will need something similar to help remove the boat from the trailer, build a cradle underneath, and then place it back gently afterwards. 

Is this something any of you lot would be interested in using after I have finish with it? Mind you, I intend to have boats and trailer for many years to come so I have no doubt I'll use it at least a few more times after this job.
