Loonsong,
Porros are the way to go. And contrary to other advice here, I don't recommend you rush into buying something on the principle you will buy more anyway in the future. $300 is indeed alot of money. You want to buy the best bins for you and that takes hands on research and time! You don't want to become obsessed with bins instead of birds! and you don't need bins you find not as good as your best pair in your closet!
You mentioned some of the Porros you tried had bad alignment. Can you say which models? The cheaper bins widely available from Kmart or Walmart will have these problems. Is that the type you mean? Maybe a $50 Bushnell? Here are a couple of quality Porro prism designs you might find at the birding stores you mentioned before which carry Swift:
Swift Audubon 8.5x44 820 (the Porro version):
It's probably the best optics in your price range. But, it's size is not suited to small hands. The eye relief is short -- probably 14mm, though its advertised as 17mm.... Even if you don't wear glasses, you may have to lower the eye cups. The result is sometimes there is glare from stray light against the ocular lens. However, these are the best bins I have found under $500 and I use them every birding day, with pleasure, for 2 years now. But, they may not be for you give your criteria in your first post. Also, they come with a terrible case.... But, I think they are the best.....
Swift Ultralite 8x42 Porro:
These bins show alot of promise. I may get a chance to try them this weekend, will report back if so. Meanwhile read this review of both the roof and Porro versions of the new Ultralites:

Notice that the reviewer concludes that the Porros are "significantly sharper" with less color fringing and they cost $50 less. The field of view is a bit narrow for Porro bins however. They seem to be comfortable design for medium size hands.
