Chris: Regarding pumping or using tanks.
I have a couple of hand pumps and use them once in a while, but I got Air tanks long ago. Much easier.
When I (oritinally) checked the closest place to fill 4500psi was in Eastern NY, or at Lake Winnipisaukee (near it) in NH. I ended up getting my own compressor (A Bauer) - Not the most economical choice but very convient.
Now there are some middle of the line ones but at the time it was a shoebox compressor or a full blown dive compressor. A SB gen II with filters would have run me close to $1600-$1800 but was 1/100th (Yes, 1%) of the speed of any of the small dive compressors for 3-4K. So although more money, the dive compressors were a much better buy and had better filtering, etc. It would take basically a day to fill my 97cf tank with a shoebox. I can fill it (3000-4500) in about 12 minutes now. The Shoebox also needed a first stage compressor. The new Alpha 90's look very nice and if they had them at the time I probably would have gone that route. The Shoebox's (at the time) also needed frequent maintenance (every 4hrs I think). I think the original at $600 (plus some filters) was a great little compressor but once it went up over a grand (without filters) commercial compressors become more of an option.
The Alpha looks like it's (slow) enough to directly fill the PCP's without a tank. A good tank with all the fixin's will run you $400-$900 depending upon the size, valves, gauges, hoses, etc.
If you end up going that route talk to Joe B for the tanks - Quality stuff, reasonable prices, and he's a wealth of knowledge.
Also, if you get a tank(s) you'll need to hydro test them every 5 years, should get them visually inspected at least once a year also. Currently Carbon fiber tanks can only be used for 15 years but DOT is reconsidering that due to feedback from various agencies.
