Hi Mal,
Can't think of anyone on here who uses them, I have seen a small Dremel "scrollsaw" but to be honest I don't think they are suitable for doing proper scrolling as they don't have a very large table.
Your best bet is looking for a secondhand Hegner/Axminster/Delta etc what sort of money do you want to spend then we can keep an eye out for ya?
Cheers
Brian
