    Changing out a 1988 Deore rear derailleur - what do I replace it with?

    I have an old deore rear derailleur on my old trek 830 that is starting to take a crap. It is on a 6 speed freewheel set up and I would like to replace it with something more or less cheap - I ride 80% on road/trails so I don't need anything bullet proof. It does have the SIS shifting system so its indexed. Can I buy another shimano product and expect that it will work OK or is there some specific specifications I need to look for? I know I should probably get a new bike but in my budget it looks like the components that come on bikes nowdays are pretty rudimentary (HardRock and 3500 trek) plus I need to shell out $$$ for some other expenses now as well. Anyhow thanks in advance for any help!

    needs to be shimano, 9s or less. If you could find a deore model, that's what I would get.

    something like this:
    Shimano Deore M591 SGS Long Cage 9-speed Rear Derailleur Silver - AEBike.com
