With enough practice, it's possible to solder very high-pitch parts and not 
get a solder bridge. The nice thing about the reflow process, is that parts 
tend to center themselves on the pads due to surface tension.

Also consider that you can bake several boards at a time, so you save 
yourself a lot of time and effort by not having to hand-solder each pad. If 
you need to make more than a few boards, Shawn's suggestion to use a stencil 
starts to make sense.

Whenever we need more than a few prototypes built, we use Advanced Assembly. 
They're pricey, though -- last time we paid $50+ per board for 10 small 
boards.
