Any Puzzle Bobble fans out there?

I ask because I'm itching to jump into this Bubble Bobble spin-off (called Bust-a-Move in North America), but I'm not sure where to start.

I know what some of you are thinking: Start with the first one! Don't worry, I will. But I'd also like to know which of the series' 26 iterations are considered by fans to be the best.

I'm especially interested in versions that were released for the Dreamcast and the original PlayStation, by the way, although I'm willing to consider those released for other systems (even handhelds), too.
