Do The Dsms Break Down A Lot?

I've been checking out some of the older posts and it seems like people are having a lot of problems with their cars (belts breaking, heads crapping out, etc). Are these cars more prone to breaking down? Just trying to find out more info buy I actually buy one. The last thing I want to do is follow around my DSM with a bucket of parts (I did that with my very first car). I dunno, from the reading I've done in the forum, it looks as if some people are just having a rough time with their DSMs... but it could just be bad luck.

What are some of the more common problems these cars experience as the miles start adding up?
