I got a IS612 a bit over a year ago. I got nearly everything except the knife and digitizing probe. I could do without the remote pendant, it's fine, just not as needed as I thought. I wish I had the 10 tool ATC, just for having extra redundant bits to speed up broken bit changeouts, but with the automated tool measurement, it would only save 1 minute per change out. The 2,000 IPM travel is fantastic, but a little terrifying if coming from something several generations ago! Great for punching mounting holes and stuff, but in reality it only moves marginally faster than the Pro series due to feeds/speeds, like Johnny said. Make sure you're getting the larger spindle and mister options for aluminum cutting, the set of tools they sell signmakers are fine, though I've only truly utilized 3 of them.
Also I think the Becker pump is superior to the FPZ for a warmer climate. NJ may not have the issue, but they don't want the relief valve to intake air above 104F, which in an enclosure with the sun on it here, 104 isn't hard to hit. I never looked into the Becker pumps, but I believe one of the techs mentioned in passing they were fairly bullet proof, where the FPZ is sensitive to temps. We already had to ship out FPZ to the factory to get rebuilt when its intake pulled in the hot exhaust and caused some scorching on the turbine.
Also the 25hp FPZ draws 900 amps at startup. Nobody told me this... We spent $2k in hardware plus electrician costs to make that connection.
