Hi all, I'm looking into getting a quickchange handpiece for my foredome and I'm wondering if anyone has experience with multiple models?

There are four at the moment and I'm not quite sure which one will fit my needs best. Leaning towards the H18 since it doesn't require lubrication and is slim. I've only used the basic H30 one that ships with mine when I bought it. Feel like I waste a lot of time changing bits.

For those who have changed from the H30 to a slimmer model do you find you like that better?

Any reason not to go to a quickchange? (Besides the obvious drawback of only 3/32 shanks).

Heres a list as a refresher http://www.foredom.net/quickchange.aspx

Any input is appreciated.
