I have used SBIG ST402ME, which is a very good unit. Perhaps a bit heavy and the power and connectors are a bit cheap and likely to be troublesome but cooled and sensitive and almost always gets a guide star.

Lodestar - has been a bit problematic but is promising once sorting out the darks for it. I don't think its that compatible with CCDsoft.

Fishcamp engineering - quite good, fast, reasonably sensitive, slightly heavy but lighter than ST402. Version I had would freeze but a firmware update is supposed to have fixed that.

What are others using good or bad?

I am also wondering if these new USB 2.0 DBK 618 colour cameras make good autoguiders as well?

They could do double duty -planetary or autoguiding.
