Hi A&C
The Aspen is a great bit of equipment, and is the cheapest way of getting a full PFD in an aircraft. With the recent announcement of the multi model EASA STC available to allow installation in lots of different types without additional paperwork costs. Very feature packed and will interface with most existing aircraft avionics.
I would suggest knocking on the door of one of the Aspen dealers around the country, if they are serious dealers they will probably have a demo unit they can show you (either on the bench or in an aircraft).
The guys at Fairoaks showed me their demo rig and they are worth a call if you want to see one at work.
