Yeah the AT Pro 25 is a good mic. I've been thinking about picking a couple up for live stage mics to use on my floor toms. I don't like the Beta 52 on kick for my style of playing, I find it's more suited to Heavy Rock and I've got the CAD for that at less than 1/3 the price.
I'm not familier with the Superlux mics at all, I'll have to check them out at that price to suggest to friends if they're any good.
One other mic that I forgot to mention tho I don't have personal experience with it, but Dennis over at the Long Island Drum Center raves about it as a high quality entry level kick mic and that is the "F" series from Audix. I believe it can be had for about the price range you are talking about. Dennis sells them for aroud $70 and LIDC doesn't have that much of a turn over on mics and electronics so I'm thinking that it may be cheaper at one of the bigger Pro-Audio sites (or not). I believe it is the F 12 but I'm not sure about that.
If you can score an AT Pro 25 used for around $50, that's also a good way to go. New they are in the $80-$90 range.
Another possibilty, and this is a stretch; an Oktava MK319 (large diaphram condenser) can often be picked up on sale at Guitar Center for under $100 and a jazz drummer that I know uses one backed off from his kick and gets incredible sound. The reason that I mention it is that it is a multi-purpose mic that you can use well in other applications.It tolerates low frequencies well and for some people it is an excellent vocal mic. I use its simpler brother the MK219 as my floor tom mics for recording at home. I use only dynamic mics live.
