Pilgrim101,
The best place to get a response on Shadows is probably on the BMAA bulletin board at
http://groups.yahoo.com/group/microlights/
The CFM (and therefore parts) situation has been confused for months now, with various rumours doing the rounds as to what's happening.
Shadows themselves are fun (and easy) to fly. Visibility from the front is great; just like sitting in a glider. Access to the rear isn't good, especially in the narrower CDs, but it's OK-ish once you're in. The in-line seating means that they're not the most social of aircraft if you're taking a friend along, and they are rather noisy, especially in the back.
Endurance is a problem, though you can fit a second tank (weight permitting) beneath the rear cockpit which brings the range up to about 3 hours.
If you're just looking for something for fun flying, mainly on your own, and don't plan to cross continents then Shadows are great.
Having said that, people have crossed the world in them of course. I was at a fly-in in Ireland at the weekend with Brian Milton who had all sorts of tales about his journey in the
Dalgety Flyer.
