I'm looking at Dremels again. Did a few years ago and there were so many
models, I just put it off.

Now, I'm interested because I have occasional use for one. Corded or
cordless? I'm leaning towards cordless, though I see the see corded
model has a quick release mechanism that obviates the need to use the
little wrench on the collet nut to change tools but, on the other hand,
all the collet sizes are not readily available if you need a different
collet.

So, I don't have enough info to make a decision on this yet. Just like
the last time.
