Unbeatable for the price! Should be ok for low focal lengths, perhaps 50mm?

Great how long can I expect to track for?

Realistically, you'd be very happy to get one minute out of it. Be aware that the economy drive is not stabilised at all so you have to keep adjusting the pot until you get the tracking rate right. I would go for the more expensive one with the separate multi speed handset.

from 50mm and shorted, if you can get the mount properly polar aligned and everything setup properly, then 2 or 3 minutes is possible... just about. I agree with Themos, if you can, go for the more expensive motor.

With DSLR and 55mm, I managed 4 minutes once after careful polar alignment and some iterations of adjusting the speed knob. Details in this thread:
