I didn't want to post this publicly and start a fight, but do yourself a favor and ask for recent customer references from Aviomania. The machines are really well designed, but I don't think they've delivered more than about four complete kits in the US. Some buyers have waited a very long time for parts after paying for them, and report long periods when e-mails have gone unanswered.
The 582 should be plenty of power. I fly an old Vortex at 5,000' above sea level and weigh 190 pounds, and it's no rocket, but would be much better closer to sea level.
If you wind up with a Vortex, I'd highly recommend removing the pod for your first flights until you get a feel for the machine. The pod makes it more comfortable in cold weather or extended trips, and makes the machine a little faster, but it's less stable in yaw, which could be added workload for a beginner. Otherwise, I've found the machine a joy to fly.
See you in ground school! (Or, more accurately, hear you!)
