home page links
PRx or better links (where x is usually 4)
links from penalized sites*
links from banned sites
URL only links
Anchor text only (no description)
cross links
deep links
traffic only links
PR only links
google bombing links

* does not indicate I actually believe in penalties, I think pages just score higher or lower in the algorithm according to changing parameters
