MP3 HU Comparison

OK folks.. need some help in deciding what new MP3 HU I want.

My 3 picks so far a


Clarion DXZ838RMP

Sony CDX-M850MP

Kenwood KDC-M7024

All are round the £220 mark and have similar features and functions.
Any recommendations or discouragements to those units about or are there
any others that I should take a look at.

Any help greatly appreciated... I'll be having a pop into my local
Halfords to see what they have to play with (don't worry I won't be
buying anything there).

Cheers.
