Finally!!
Just got off the phone with Mitch Dexter, Sales for Nuvair. I placed an order today for a new ICON MCH-6 three horsepower electric compressor. 230V, single phase unit. Electrician installed my dedicated 240V single phase, 2 prong 30A circuit in my garage, right behind my work bench. It will handle the start up load and steady state req't for 17A easily as a 230V/30A install.
Price increase effective today. Good thing I got the quote 2 months ago, and Mitch did what he said. He told me he would honor until I was ready. My unit base price w/o some features I ordered was $2970, and price effective today was $3500. I did order an auto shut off switch set to 4700 PSI and lengthened the power cord from 6-8 feet. Got two adapters, one for each tank and associated fill valve. It comes with the standard 300 DIN male which works fine for the GW HP3 valve. The 6.8 L has a foster male for compressor filling, so I got the adapter needed for that as well.
Feel like a little kid. I picked up my two fill tanks ( GW 9L and Tuxing 6.8L) from the Carolina Dive Center today, filled to the usual 4500 PSI. Told the manager, I might not see him for a while. Feel bad in a way, I have been going there for about 8 years once every 2 or 3 weeks. They were great folks and almost always filled, and topped off after cooling to 4500 psi, while I had an hour lunch. They accomodated me so I would not have to drive back the next day. It's a very busy Dive Center and they have a lot of Scuba tanks to fill, so I appreciated the nice touch. Still, I'm getting over it as I type.

Hopefully, everything works as planned. Once I get the compressor, set it up and use it a couple of times, I will do a review.

P.S. I mentioned to Mitch and Craig, to consider getting a userid / PW access to AGN. There is great value for us and them in having them monitor this thread from time to time. Sent him a link today to get started. Great guy, very responsive and could not have been more helpful.
