The blue one has a certain something about it I quite like.
That 3-pup expensive one has definitely got some Zeta in its DNA. (The one in the middle with the hard case, not the one at the top.)
Yes, that's a BEX 4. Rotten pictures, the last is the only decent one. I'm reckoning £350 is about the most you should pay for one, personally. But I'm notoriously cheap.
(That's not mine, I'm not selling!)
