Before deciding you should really find a shop with more than 1 brand, so you can choose your favourite. Hudy, Orion, Eagle, Reedy... there's a few candidates. They differ in build quality, machining, materials and price - but they all do the same job.

V-guides or bearings? Your choice!

Most of them have interchangeable bits anyway, so you don't have to buy a bit from the same brand.

Diamond tips last a lifetime unless they're broken prematurely through careless use, then its trash. Carbide tips need re-sharpening regularly so you'll need to know someone who can do that + budget for the $$. Haven't compared them side-by-side but I'd say a new carbide tip should cut as well as a diamond; but results may differ as it blunts.

LHS here has Hudy's diamond blade for A$240... ouch!!


Some come with drive motor, some don't. Most run off 4-cells, but there are some motors designed for 15000rpm @12V too.
