Also a fan of USA's Burn Notice, which just kicked off the summer season with new episodes.
Another fun show is TNT's Leverage. Con artists as modern Robin Hoods. Set in Boston, but filmed in Portland, OR (my two favorite cities).
We also watch Bones and NCIS, both the new and syndicated episodes (on TNT and USA) and have given NCIS: Los Angeles a second chance (it's grown on us).
It's no longer on TV (even in syndication), but if you're a fan of J.J. Abrams, Alias is good fun. Was disappointed in the final (5th) season, but the rest of it was really quite good. Ought to be available via Netflix or your local rental place.
