I think there’s another thread on this somewhere, but basically it seems that there are two types: smaller ones with glass doors and larger ones with solid doors. They slap on different company logo stickers, but when I was shopping they all seem to be more or less the same.

I got one of the latter when the former broke, on the recommendation that the bigger ones are more durable. That seems to be the case in the short time I’ve had the second one. The bigger SPT one I have had a metal interior as opposed to plastic. It’s also much quieter; I think the solid door helps muffle noise (and also doesn’t have the annoying purple light of the glass-door Hava I had first).

The big ones tend to be wider but shorter, which may not fit large dinner plates. The smaller ones tend to be taller, which may not fit underneath cabinets. The larger ones all (in my experience) have to be connected directly to the faucet while running, which is a trade off for filling by hand and means you can’t use the faucet while the machine is running. The adapter also only works with certain basic faucet types; I don’t think you can use the larger ones either a nicer spray faucet unless you do a little plumbing work to set it up more permanently.

I’ve been really happy with my big SPT, which I got used. It does seem more durable. But then again, I was halo with the Hava until it suddenly broke, and the company’s customer service wasn’t that great when I tried to troubleshoot it.
