A multicut 2 would be fantastic with variable speed. A lot of people dont have variable speed and dont seem to miss it but I seem to be constantly changing the speed whilst cutting different types of wood and of course different thickness. I have some 5mm aluminium to cut for a disk sander, im sure it will be useful then as well.
I havent got a Hegner. I purchased the Excalibur 21" from Axminster. A lot of people report reliability issues with it but it has never had a hint of a problem for me. It has a few features that are not on the Hegner, being able to tilt the entire blade assembly over and keep the table perfectly flat is a major boon for instance. There are a lot of Hegner "snobs" for want of a better word that dont seem to acknowlage the existence of any other quality saw, but horses for courses I suppose.
I wouldn't think twice in buying a good second hand Hegner if I needed another saw, they are fantatic. You do seem to see a few on ebay very regularly and they are very robust. I wouldn't be without the Excalibur though maybe I've just been lucky and not ad a Friday afternoon one?
I found Dad an old NuTool one circa 1980 for £25 that is bomb proof, weighs a tonne, so no vibration and it was easily converted to pinless blades. Not sure id even look at the newer NuTool stuff but Dads is excellent and proves there are bargins to be had if your lucky enough to be in the right place at the right time
