Over your budget, but for what it's worth and future reference, I've got the Ryobi EMS254L. Retails for about £275. It's a 10"/254mm blade, fairly solid, and I've found it to be accurate enough (to the point where I've built it in to my workshop). It has a laser, but that's not particularly adjustable and so fairly useless. It's big plus is that, although it's not as snug as the Bosch articulated arm, its parallel arm guides run forward rather than back, so it can fit pretty close to the wall. The biggest minus for me is that the dust collection is atrocious. I've not used other mitre saws so I can't compare directly, but (even in a category of machine which is notorious for bad dust) I suspect it's poor in this regard.
So, has it served me well in the 2 years I've had it? Yes, absolutely. Would I buy it again? Maybe if I wasn't likely to increase my budget, but I'd be very tempted to sell one of the kids to a chimney sweep and buy the Bosch beastie.
FYI, there's also a cordless version (their One+ 18V range) at only £236 (w/o battery), although on closer inspection that's only 8".

In my experience all mitre saw dust collection is atrocious. I see a lot of joiners build them into a kind of funnelled box with a 100mm port on the back.
