I have two Dremel tools, both started life as the mid-price kit. Believe around $50 US, or less.
Used once for detail cleaning/polishing of four chandeliers, worked great, but you need patience.
Great for sharpening, also great for cutting tile, laminate panels, SS if you're patient. I have not tried it on sheetmetal, but it should work.

Carbide cutters survive pretty decent, the diamond accessories are a strong survivor.
Used within it design limitations, it's a worthwile extra tool.
Oh yae, saw a 'deluxe' kit with lots of 'pieces'; think it was <$90 US.
The kits include a lot of cutoff disca, and sanding discs, which they count as each piece.
