I had a Dean Edge 4 for a very short while. Actually, it wasn't mine - it belonged to a friend of a friend, who wanted me to do a refinish.
Anyway, I played it a few times before I took it apart. It wasn't a bad bass. The body shape and overall style weren't really my cup of tea, but it played fine and sounded ok. The neck seemed really wide at the nut to me, although the neck itself was pretty smooth and felt nice.
IIRC, the newer models are up in the $350 range, which puts them in Classic Vibe territory. I haven't seen and/or played many Deans, so I can't comment on their overall quality control. I've heard both good and bad, though.
