Help picking a metronome

[8bitrevolution]

I'm trying to decide on a metronome and was hoping that some of you who own the ones I'm considering could give me your thoughts on them. I know my v-drums have a great metronome built in but I want something that I can take with me when I travel.

I'm considering the Boss DB-90, Tama Rhythm Watch, and Korg Beatlab. I like that the Beatlab has the rudiments programmed in for practice. I like the idea of the DB-90's ability to hook in v-drum pads but, at the same time, I know I probably won't use that feature often if at all.

So, any owners out there who want to share their experience and recommendations? I'm mostly concerned about useful features, ease of use, durability, and battery life. Also, I'm especially interested in reading more about the Korg - it's the one I've heard the least about.

Thanks!

Korg Beatlab video (french? but good enough to get the idea of the rudiment feature): http://www.youtube.com/watch?v=-GfxDYVWjnI

Roland has a nice video showing the differences in the DB-30, DB-60, and DB-90: http://media.roland.com/en/v/v0444/v044402M.mov

I personally just picked up a DB-30. Very compact for on the go and very easy to use. Hope the videos help with the decision.
