Don't know how badly your surface chews up blades, but a two piece stick is usually what I'd recommend for roller hockey players.
I personally like the Easton Cyclone, it's the lightest shaft Easton makes and the shaft shaft is less boxy than others which helps since I have relatively small hands. Shaft will cost around $75. For blades, I personally like the CCM V-20/V-40/V-60 as they wear down very well and they're relatively cheap $20-$30.
The Mission L-2 is another one I've been wanting to try. It's a tapered stick and tapered sticks generally behave the same one piece sticks, but you have the ability to swap blades. The L-2 also comes with 2 blades for ~$170. The shaft alone sells for $100 and each blade is $50. So it's a decent value.
But like the other guys have said, there's nothing wrong with a nice $35 Sherwood woodie. Somebody with noodle arms like me would notice the weight difference, but most guys won't.
If you can hold off for a few more weeks, the 2006 model sticks will be coming in. And there will be some more options in each price range.
