I wouldn't bother, to the extent it is almost tiresome to explain why.
Yes, it's 3" blades. You won't have any problems getting them online, you'll likely struggle getting them locally and/or in a hurry. However, they are quite spendy and you won't have a great selection available in terms of TPI or material to be cut. Looking online no-name 3" blades cost more than best of breed 5" blades even by the dozen, much more expensive than those same blades by the gross. The Dremel blades are twice the price of even the no-names.
It's a sprung top arm model. Those are mostly older and lighter duty models. They have their place but...
It's big. The other sprung arm models, e.g. from Aeropiccola or Spiralux at least have the virtue of compact size. Obviously that limits the size of component you can cut but you can put them back in the cupboard when done. This is basically the size of a regular scroll saw. Where's the benefit?
Forget perceptions build quality, I'd strongly prefer a random 16" throat, 5" blade saw you regularly see for £20 used on ebay. For £50, well for perhaps £20 more the likes of Aldi and Lidl regularly have new saws going new with three year warranties.
