favorite MST3Ks?

So, I'm going to order some tapes from this guy, and I googled for an hour or so to try and find lists of top fan-rated episodes, but damn, it was hard. I found some scattered results, but nothing jumped out at me as especially useful or definitive. So, I'm wondering if people have any recs? What are your top 10 or 20 favorite episodes? And, actually, I'm really only interested in ones that haven't aired on SciFi and aren't available retail.

The link above has a tape list w/episode titles, and there are lists here at the official fan club web site.

Also, if anyone has any links to web sites where the episodes are rated, that'd be cool too. Any help much appreciated. :)
