Where are you finding sanctification in Oceanside? Just missed out on the last release here but my mom and brother still live down there and I'll have them grab me a bottle.
Oude Tart is a good one as well from the Bruery. Rodenbach, Petrus Pale and Monk's cafe are good starting points as well. Almanac is releasing a new sour everymonth now and everyone i've tried has been great, although I've heard from multiple people that the Sourdough release needs some age so I haven't opened that one.
Be wary of what you get a BevMo, as with a lot of beers they may have been on the shelf for a while. I had a bottle of Duchesse from Whole Foods that was turned very acidic and vinegary and would have turned me off of sour beers if it had been my first.
As with any style - don't judge them all by one beer, esp sours since they have a huge range of flavors.
If you make it up to the Bruery you can do flights at the tasting room which would give you a good sampling.
