Anyone know what it's like? http://www.rutlandcycling.com/16670/Scott-Sportster-P6-2010.html

I've been looking for a cheap-ish bike suitable for road riding for ages but can't find anything for my low budget of around £300. As I'm coming from a mtb and bmx background I hate feeling stretched out so I don't know whether I'd want a drop bar bike. Not really sure on road components so are those in the link above (click description) any good or is it all gonna fall apart after a while?

My main priorities are:

-comfortable on bumpy (ish) country roads
-gears that change properly
-brakes that'll slow me down if needed
-fast rolling with hubs that won't fall apart

Will this be suitable or does anyone have any other suggestions?
