I sample with my racking cane (I'm cheap). I just immerse one end and suck on the other end (with my mouth) to draw liquid up, block air with my tongue, and pour into a glass waiting in the other hand. Small samples, but it's good for tasting (not enough for a hydro sample). AHS sells a stainless steel racking canes that can be autoclaved, and I've considered getting one for ease of mind when messing with brett/bugs.
The turkey baster is probably a better idea because you can't get your spit in your beer on accident.
