Infinity 2 in 1 vs. Colani

[MrGrinch]

Hi,
Trying to figure out which of the two I should get. I'm a beginner but want an airbrush that will suite me for a while (ie doing small detail and larger area). I also want a comfortable airbrush as my hands shake when they get fatigued (and they fatigue pretty quickly)

Here are the pro's of each one I could see:

Infinity
Quick Fix Feature
easier to change needles?

Colani
More comfortable grip style.
Ability to switch from gravity feed to side feed.

Am I missing any cons or pros? Which would you pick and why?
Also why hasn't anyone reviewed the Colani? Is the Infinity just that more popular?

Thanks,
Paul

Its only been available here in the US sense Feb.(Colani)
everyone I know who has one loves them
infinity might be a bit of over kill for someone starting out
