I would go with the 4500psi, the compressor has a burst disk installed so a 3000psi unit would not be able to go much above that. They fill slow enough that keeping an eye on fill levels should not be a problem.
Scuba tank – 21 hours from empty
Scuba tank – 5 hours from 2000psi to 3000psi
I think someone suggested adding a bust disk in the fill setup for safety.
It takes a little time to get posting rights, not many folks getting on the list now so it shouldn’t matter that much.
The original order list, you can get on this to be in front of the line for next order: http://www.automags.org/forums/showthread.php?t=251401
post #127 he states:
At this point we have as many orders as we can handle for this first run of 100 units. Many people are not getting back to us with payment etc so we don’t know if this is the actual end or not. Your welcome to continue to sign up here but we can’t guarantee you a spot in the first run. We will however take you first in the next run in about 8-10 weeks.
