Presto Sim: anyone here train with them?!

[formulaben]

I've been contacted by a school in Dallas, TX (USA) for a CE500 recurrent, perhaps with a Single Pilot Waiver. I'd like to get as much info about others' experiences at Presto Sim. Any input is much appreciated.

Why would a wannabe want a Cessna CE500 Citation rating - let alone a renewal? I'm curious. This is a very old aircraft type, and doesn't seem likely to me to be the sort of thing used by organisations that would employ 200-hour pilots. Or am I wrong, and this is normal in the US?
