If you've been riding for a while, I'd say a modern 600 would be good for you. That 900 isn't bad, but you could find 2000ish model 600's for the same price. And besides, I think you'd be much more happy with a newer bike anyhow. Older 'liter' bikes are more of a collection bike, and honda RR's seem to retain their value pretty good.
The thing is that modern 600's is just as potent as old liter bikes, so it wouldn't seem bad finding a newer 600. Can't go wrong with 20 yrs of dirt bike riding under your belt.
Oh btw, newer 600's should out turn that old 900 easily.
