A friend of mine picked up a fazer600 a few weeks ago, and it's a great bike more of a touring position than the race-rep 600's though.
As was said, if you like the position of the B250 you cant go wrong with a B6 a fazer6 or a hornet6.
If you're set on a racier bike, the CBR600F is very sporty, but still more useable as a commuter than the CBRR's
Edit:
you're in ireland aswell, if you are looking at a bigger bike look at getting it in the uk as prices are more realistic, and they MOT bikes so you're less likely to end up with a lemon (or buy my SV650s so i can get a bandit6)
Remember Hibernian just pulled out of the irish motorcycle insurance scene, so there's only two companies left insuring irish bikers from the end of july Carole Nash and AON, so factor in the likely increase in premiums that are on the way. :(
also join up on some irish bike lists/forums if you haven't already
the yahoo group : motorcycle ireland is an excellent mailing list, and
www.irishbikerforum.com was set up recently to give irish bikers a place to congregate on the web and discuss irish-specific issues without being lost in a sea of aussies yanks and brits.
(no offence to the yanks aussies and brits on here)
