Any good AliExpress ultrasonic cleaners?

[exmadscientist]

I'm finding myself in need of cleaning some stuff that doesn't quite fit in my existing ultrasonic cleaner, and I don't much want to pay for a new Branson CPX3800H. (It doesn't help that the last time I decided to "just pay for a good one" I bought a Branson 200 and got burned, because the Branson 200 is rebranded trash.) There's a ton, an absolute ton, of ultrasonic cleaners on AliExpress/eBay/Amazon/etc, but a quick look isn't turning up anything that looks worth buying.

Things I expect to see in a good ultrasonic cleaner:

• Timer (ok, they all have that; digital is much easier to use)
• Heater (yep, not hard; don't really care if it's bang-bang or digital control)
• Degas mode (not always wanted, but a decent sign that the product was intended for professional use)
• Swept frequency (there is some debate that this doesn't really do much, but I have in the past had trouble without it)
• Don't care: "soft mode" / intensity control
• Fits ~240mm long things in its baskets
• Budget: less than that damned Branson

I'm not exactly using this for semiconductor fab clean room work so I don't need the best. It's just hard to sort through the mass of these things all with terrible search functionality and no obvious brands or real reviews on them. Anyone found a good one?

Anything in particular noteworthy about those guys? They look like the rest of the AliExpress specials but with higher pricing than I've seen in a few places (which may well be warranted). I only saw one 6L model advertising swept frequency and it was listed as discontinued.

They have local stock and might honor their warranty. But if they don't have swept frequency, and you need that, then will have to keep looking.
It looks like they have "adjustable frequency" but its a manual toggle.
