Are there any decent looking ungraded T206s out there ...

There are plenty of untrimmed raw cards for sale on ebay, and there are plenty of graded trimmed ones. In most cases, unless you have severe vision problems, if you are depending on SGC and PSA to tell you that a trimmed card is trimmed, you shouldn't have mailed it to them in the first place.

Not knocking anyone, as I have very poor close-up vision, but my 10X loupe usually does the trick.

Ones that come back EOT, or assumed trimmed because they got an "A"?

I've picked up a few nice ones that would only be "A" because they don't meet the min size. But they're not trimmed. (Including the one advertised as trimmed )

I've had pretty good luck, maybe a couple trims, but also a few really nice ones. - Depending on where you draw the line for "nice" Certainly cards that would be solid 50's are out there, and I've had a few that were better, 60-80.
If you're looking for cards to buy and grade, you really need a large monitor and a browser that lets you zoom in. Many scans aren't good enough, but a lot are good enough to give you an idea of edge quality which is what you're looking for to avoid trims.
