Here's a deal that's hard to beat:

Oh - the 27T MAX is BS - it will handle a 32 without a hiccup.

Rear derailleurs are pretty interchangeable, especially for 8 spds in the back. Depending on whether you have a triple or not (I'm assuming not, as it's an older derailleur), you may need a longer cage. Also, many new derailleurs are set up top-normal, so they shift backwards. In other words, they're at rest on your large cog and shift toward the small one.
