I want to get an iphone dock speaker system, but really don't know what one to get. My budget is no more than £150. these are my shortlist would be great full for input on these and compatibility issues if any 
Sound is obviously most important with tight bass and im really not fussed about other features.
KitSound Boom Dock iPhone / iPod / Touch Docking Station Speaker System £89.99
PHILIPS DS8500/05 Fidelio Docking Speaker for iPhone/iPod - White £128.99
Sony SRS-GU10 iPhone/iPod Speaker Doc £80
