I "think" I may have a notched-but-not-horribly '03 basket stored away somewhere. Don't know if it is in better shape than what you have though.
You can have it for the shipping fee if you like.
And yup, the hub is about $50 from Suzuki, they wear out, but not nearly as fast as the basket. The better shape your basket is in, the longer a hub will last (less clockwise/counter clockwise slop).
*Don't ride near as much as I use to... bought our '03 RM250 new and replaced the stock basket with a quality Hinson within the first year. Since then I've removed some burrs off the outside diameter of the stock hub once or twice, but it's still good... (260 hrs on the bike.) I'm sure the Hinson basket has helped the hub's longevity.
