I think the Vessel looks pretty cool - I don't have one though, so I'm not endorsing it.
i hear good things about the Dewalt gyrosscopic driver too. Here's
an article about it.
What I actually have is the Dremel (also sold under Bosch branding):
Ignore Dremel's description of it having "power settings" - what they actually mean is that it has a six-position clutch. It works and it's useful. It's also push-to-go or button activated. Both work well.
What it doesn't have is any speed control. that may or may not matter to you. E.g. if you have lots of spinning to do, you might want something faster to run down the fastener in a hurry. If you're working on very small an delicate screws, the clutch might not be fine enough to compensate for the single-speed drive. Work somewhere in the middle and you don't really miss a speed setting.
It's reasonably torquey too - certainly no wrist-breaker, but enough that your screws will actually be driven.
