Plenty of money- there was one on here for 70 odd the other day.
If money is tight, spend a little on a used 3 wheel bandsaw on eBay- the makes are much of a muchness. Get a decent blade or two from tuffsaws and away you go. Depth of cut won't be massive, but probably triple or more than the scroll saw. A cheap and chearful one will do all you need and won't cost a lot at all. Don't skimp on blades- even if new, they are probably rubbish. You will probably have to tune the saw, but it isn't difficult- I managed to do it from knowing nothing and got good results following a guide online.
for example- look around £22-£30
