I won't trash any of the mics mentioned because they all have their uses for different sounds.
Most drummers will prefer the AKG D112 over the Beta 52 because it doesn't have as much of a biased
personality. The AKG will give more if the sound of the reverberation off of the shell and a distinct click to the pedal as well as the heavy bass undertone of the kick drum(great for blues, folk/rock, some jazz,etc). The Beta 52 gives you a loud thud (perfect for heavy rock). The Sennheiser is $200 more money and is a really good mic (I actually like it on floor toms, wish I could afford 3).
I'm sorry, I know nothing about
the Beta 52A but I bet we all will before this thread ends.
Check out
the Audix D6 for a really great heavy rock kick mic that also works well with all other styles or the ATM25 which is the mic I use and prefer (better for blues and jazz tho).
Also check out a pretty good $50 kick mic,
the CAD KBM412. It beats the hell out of
the Shure PG52 (at half the price) and works relly well when you want a dominating heavy kick sound behind a "shredder" guitar. (It's a heavily biased personality mic)
It won't be for all tastes, but for $50 it's another good weapon in the arsenal.
