Jolly Pumpkin does some awesome stuff. I especially like the Bam Biere, which is obviously made in the style of Orval.
Gueuzes/Lambics from Cantillon are always good. I prefer Rodenbach Grand Cru to the Duchesse for Flanders Reds.
I did a Bam Wheat clone 2 years ago since it was my favorite of of the Bam series. I brewed 6 gallons for some reason, lucky for me because my carboy of ready to drink Bam Hefe broke and all I was left with was the gallon jug I had saved.
As for funky beers it still has to be Orval. As for sour I love Rodenbach Grand Cru and the Duchesse, Drie Fontein, and just about any others. Cantillon Lou Pepe 2003 Kriek is calling for me from the beer fridge as we speak.
