I also have CosVox...it seems like we have very similar builds! I will second your statement - the CosVox is a great media device for cosplaying and comes with a great microphone and amplifier if you buy the full kit.
I would like to add Battlefront II (the new one) to your list of sound sources. Temuera Morrison did all of the Boba Fett lines in the game, a lot of which work well with a Jango build. I didn't even think of the star wars bounty hunter game for voice lines - even better!
[USER=18246]TheViceroy[/USER] The amplifier that it comes with is a rebranded Norwii amp, which is one of the amps that is great for converting to use an exciter instead of the included speaker (if you ever decide to try that route). Gives you some flexibility 
It's been a while since I purchased it but I believe it is priced very competitively too.
