definitely go there, i've been there two weeks in may / june. take a look at the asia forum here, some reports on burma there already.
yangon is nice, shwedagon pagoda a must see, inle lake and bagan also. convenient and cheap domestic flights available on private carriers. BUT you should really spend some time and go with the local flow... i did mandalay - bagan by boat in 11 hrs, the way back by plane in 30 mins. ... new world, old world.
lovely people, make sure to spend money there for the private people and small handicraft shops and also in the pagodas and temples.

you do not have to change 200$, just the visa fee and 10$ departure tax.

bring postcards from your hometown (to show and explain where and how you live) and stickers / pens from baseball/basketball/football whatever, the locals love foreign stuff as they do not get it. make sure to mingle around with them a bit, cup of tea here and there and visit as many pagodas. people love to talk, not only politics.
