With rergards to gumtree, too good to be true sometimes, i picked up a hegner multicut 1 ( the older model, with the white pipe and tension knob at the back) for £90, the table had a few cut marks where the blade goes through the table blade probably wasnt tensioned properly too much pressure on the blade that sort of thing.
It was used by kids in a school technology department (the school was going to be demolished and the teacher took it out as the new building was getting new equiptment)
The bellows were compressed and needed stretching out again, but other than that it was hardly used, came with the hegner stand and a hegner foot switch.
It was listed on gumtree as hegner saw with no images and little description, i used about £20 petrol but what a bargain.
As for up grades i am awaiting a pipe i have on order
http://www.amazon.co.uk/Length-Nozzle-P ... olant+pipe (coming from china so might be a while) so i can upgrade the piping.
I have also made a quick release tensioner from a bicycle skewer ( wheel quick release ), had to use a couple of spacers but it works a treat and cost £3.50 rather than £38.
I kept bidding on ebay but was always outbid at the last minute, just shows never know when you will find a bargain, my advice to anybody looking for a specific make of saw is keep looking you will find one eventually, as if you buy a cheaper model you will probably only upgrade later at more expense.
