I've played bases made form plastic compounds (Bassix ones), alumunium ones, ply and fully carved ones. Personally, unless you need an ultra light bass that's resistant to changes in temperature and humidity (because you're gigging internationally) I'd avoid it. Instead, I'd buy a well cared for DB on here that's been well set up and sorted for a fraction of that price.
When you go to pick it up, tell your wife you negotiated a £250 discount which you're going to use to treat her.
Everyone wins!
