I have a version of this one, as linked to above...
mine is a sealy branded one and was a bit cheaper than that a couple of years ago... about £125 from eBay I think
It is a good, compact machine, especially for the price, but you get what you pay for - it doesn't have an automatic stop (mine does now) and it takes a bit of effort to get it set up right an cutting square (mine still dosn't). It will cut upto 100mm or so, which I rarely have need for more. I think I might be tempted to get a more expensive one, but for the money it is very good.
As well as the auto stop, I also put castors on the stand rather than the rubber feet - it makes it very easy too stash in the garage, and wheel out as and when required.
Cheers
Mark
