Ok here is my report . . .
Aoyue put me into contact with a local chinese store here in Bangkok that had some to sell.
Aoyue 2900 sold for 3400 baht, but I managed to bargain it down to 3100 baht (~$88 US).
While I was at it, I also bought the Aoyue 486 solder fan for ~$24. A pretty good deal!
I learned buying off the internet here is a bad idea - Thailand has 20% customs tax/VAT for all electronics, and shipping is a killer too. And that's assuming it doesn't just 'disappear' in the mail when you refuse to 'tip' the mailman (I'm not kidding!)
This Aoyue 2900 is probably the best soldering iron I've ever used - heats up *very* fast and *very* hot! I was able to solder almost twice as fast!
That being said, I used it heavily and it seems to be wearing out pretty fast too:http://www.societyofrobots.com/robotforum/index.php?topic=6251.0
(I created a new post for anyone who can help with that problem)
My biggest complaint is that its for 220V only, so I'll have to buy a new one when I return to the US . . . oh well!
btw, for anyone else in Bangkok, this is the address of the Aoyue shop:

Samutprakan 10270 THAILAND
call Mr. Zheng, the manager directly at mobile number +66-85-042-4848
(note: they only speak Chinese and Thai, no English!)
