Recommendation? Worksharp owners: grinder attachment vs these import mini-grinders?

[JacksonKnives]

Context: Used to have a 2x72, but live in an apartment now and no time for any serious grinding so it's in storage. I don't expect to do anything more than thin out a chunky edge on a Vanadium-PM-steel blade very slowly and carefully with a water bucket for cooling.

Was looking at the Worksharp K.O. Ed. + grinder attachment again. If it were available without the other guide for $150 I'd probably have jumped on it by now, but I really don't like that I have to buy the parts I want separately and I'm not certain that I can get the belts I'd like, though it seems like the power-filing air tools often use 1x18.

So, today I happened upon these:
A mini KMG grinder for 1x25" belts for $250. Variable speed up to about 2300SFM. "2.8 n-m torque" doesn't tell me much, and the note about a plastic brush holder melting under excessive use gives a useful gauge of how hard you can work it. This isn't a hogging machine but it should sharpen nicely... TrueGrit has belts in 30" that should fit, I think. There's a contact wheel attachment, but I'm not planning to make tiny knives...

The same Aliexpress shop has a 12" belt / 100w machine for $88, looks like this one really only works with a platen/slack setup between the two wheels, which is a shame. Basically not any better than the 30" setups you get from a hardware store.

Any thought from Worksharp owners? Would anyone rather have a small benchtop rig than the large tabletop Worksharp grinder setup?

That's pretty interesting. I just wonder where you'd use it in a small space like an apartment. One reason I bought the WSKO was so I could use it on a table top in a small space. ...and use it on the go as well. I'll eventually have a "real" belt sander setup in 1x42 or larger. But this small machine is definitely interesting, particularly because it's continuously variable with a DC motor, so it's variable *and* safe and should have good torque even at low RPMs (comparatively speaking).

Nice find.

That's the big question that kills me whenever I think about tools. I think I can wall-mount it in my garage... but I'd probably wind up using it on the kitchen countertop for sharpening and stashing it in a closet.
(As far as wife approval: 'tis easier to beg forgiveness than ask permission. If I buy a $300 tool she can't stop me from using it, right?)

I would love to see these in person. Wondering if anyone will test one?
Troubling text in both descriptions, could be the translation.
They look cool, but what do I know?
