There's a LOT of truth in what's said above about Hegner.
BUT, and it's a pretty big but, these days their design is pretty old-fashioned (e.g. no tilting head, just a tilting table, unlike the Excalibur, the Axminster version of the Excali, and now, a new Jet model), AND; by general consensus amongst experienced scrollers (many to be found on the Scroll Saw section, by no means just me), new Hegners (both new machines AND all their spares) are just vastly over-priced - the quality is unarguably excellent, but all 3 of the above-named give you more bang for your buck and are almost, if not exactly equal, in quality (build and materials). In fact one of the Axminster range IS actually a Hegner "clone", and reckoned by a couple of experienced owners on the Scroll Saw section to be every bit as good as "the real thing".
I bought an Excalibur 21 a couple of years ago (before Axi had their own re-badged but cheaper version) and before buying I had the opportunity to test both an Excali and a comparable muliti-speed Hegner in the shop's shop for an unlimited period (about 90 mins each). Personally, although undoubtedly very high quality, I choose the Excali over the Hegner (more "bang for the buck", just as good quality, AND the Excali was not only a bit cheaper, but spares prices for the Excali are "sensible", not "absolutely outrageous" as Hegner spares are now generally acknowledged to be).
But caution - we're talking about 300+ upwards quid machines here (in all cases except if buying SH) whereas a new scroll saw starter may want to consider the plus/minus 100 quid machines (some of which ARE usable - often luck of the draw though).

Edit for P.S. Notwithstanding high quality, ALL machines require spares now and then, even Hegner - e.g. the "pump" for blowing sawdust away from the cut, perhaps a drive belt (depends on model), QR blade clamps, perhaps the odd bearing (normally specials, not off the shelf). Hegner are "taking the mickey" with prices these days (not just my opinion).
