It's still being made, just not in the quantities of years past. If you want to pay full price you can still get some stuff, but sooner or later it'll stop being produced and you'll (I'll) be forced to upgrade.
I've gone through 3 chains, two cassettes. Plus, a lot more fine tuning is involved for butter smooth shifting. With 8 speed, you get close and it's great!
