personally i only have experience with Volks and Justkampers, both excellent service and aren't afraid to pick up the phone or exchange multiple emails. Products arrive exactly one week after being ordered (delivered to Tasmania). I have nothing to complain about with these two.
I haven't ordered from George yet, due to the above issues (both gpositive experiences and negetive ones). I will order from CIP1 however, due to their more extensive range and being able to find parts easier (in my eyes).

Cip1: Excellent service.
ISPWest : Ultra excellent (Type 3 parts)
Even better with dollar parity, but has always been competitive to buy on-line and ship from USA.
Just Kampers are good/reliable/fast, good and bad experiences with CVD - don't go there anymore.
