I will not recommend because it is personal preference, just like blades and all other things the deal with wood working. So many ways to skin a cat as they say.... I do fretwork on both my saws. The bigger pieces I usually move to the Seyco. You are choosing between two fine saws and I think you will be very happy with whichever you select. The newer Hegner may have some things you did not have on your retiring one, front tension, VS speed are two that come to mind. The Pegas has those, plus, top or bottom feed, larger table, tilting head. I don't know how old you are, but I think the Hegner will outlast the Pegas long term and require a less maintenance. But if you are senior,,, do you really need a saw that will last forever. That Pegas should last many years is taken care of. I know I would be very happy with either with the type of scroll I normally do. If I do heavy scrolling, like 3D, I use the Hegner. I. just think it is built more for hard scrolling and my Hegner has a little more clearance between the arm and table. I do not know about availability of parts for the Pegas, I have not heard anything that sounds like it would be a problem...
You might look at it this way, if you can afford a Hegner, maybe it would be nice to have 2 Pegas' instead!? I love have 2 saws.
