Should I get Dead Rising??

I'm looking for a new game, and nothing thats just come out really interests me, so i'm looking at older games.

I've never played Dead Rising before, but many of you continue to praise it in different forum posts.

How much could I get it for now? And because its old and some of the issues i heard it has (ie save points) is it worth buying?

It is definitely worth checking out, I bought it for like $34 but that was during the Summer. You could probably find it now for $20 or less maybe.
