That helps, thank you.
So the extra moving parts, and fiddling with voltage realy doesnt affect reliability?
Sweet!
I guess a twist is on my list

Whenever there are extra moving parts it increases the probability of something going wrong of course, but about the only complaints we've seen on the Joye eGo-c Twists is that the numbers are hard to read on the dial and there's been a few cases where the dial was a bit tight. The mAh ratings 650, 900, 1000 are for use at 'normal voltages' - ie the same as an regular eGo battery, so when you are up above say, 3.5 Volts on the Twist, you are not going to get the 6.5, 9, or 10 hours of battery use per charge. And the length will fool you - you might look at some comparison threads.... just so you know... for example:
From left to right: w/T3 except as noted
Vision 400 VV
510 cig style 510 atty
eGo mini 450 w/baby T3
regular sized 650 eGo-c
900 eGo-c
eGo RS
650 eGo-c Twist
900 eGo-c Twist
The 1000 Twist is about a half inch taller than the 900.
And as ZoiDman points out, there are variations in quality for the clones and knockoffs. My comments are about the true Joyetech eGos.... just read the other threads here for an indication of reliability. You can get a lemon in any brand but for the most part you get what you pay for.
