Looking for good UMTS phone, but not too $$
 

I'm starting to look for a second UMTS phone for my trips to Japan. I currently have a Moto V980, which works and was cheap. However, it lacks Bluetooth. Some of the new quad-band GSM + UMTS phones I've seen run over US$600, which is more than I want to spend. The SE Z610i is tri-band + UMTS and I've been seeing them for around US$200. I've been pleased with my previous SE phones. Anyone have an opinion of this model?
