I road bike mostly but my son wants to use my mountain bike for riding the roads, to get in shape mostly for football. Only problem is my mountain bike needs a new derailleur, cheapo on it now is shot.
Shimano C050, 7 spd, searched online and it dosen't look to be available anywhere.....any thoughts on a suitable replacement? Thanks,

Just about anything will work, but check that the claw hanger isn't integral to the RD. If it is you'll need an adapter or an RD with a claw.

DMF, I think the claw hanger is a part of the RD. In looking at different RD's it seems most 9Spd's say they'l also work for a 7 is that true? The bike is a Pacific but its a good frame, cheap components for now but maybe I should build it up a little as I'd like to use it more? Anyone recommend a better RD to start with?

Almost any Shimano mountain rear derailleur will work, with a claw adapter...

However, check out the TX50 for $14.50 which will work just fine for any 7 speed Shimano mountain bike.

I believe Loose Screws also sells claw adapters if you want to go with a higher end RD as well.

In my opinion, a higher end RD is not likely to give you much improvement on a 7 speed cluster, although it may save you an ounce or so in weight.
