I have another suggestion for you.  I have collected both new and vintage.  I tend to like the loose vintage better than the carded for two reasons.  One, because they're cheaper, and two, because they are cooler to look at and dispaly.  That's my opinion at least.  I treid to get into the carded stuff but I don't like the idea of just hanging them an the wall.  I take all my playsets out of the box, put the box away and display them loose.  It's kind of like you're showcaseing a piece of art.  Like a sculpture.  You don't spend as much money on the stuff either.  But it sounds like you've already started on the carded toys so I won't try to talk you out of it.  Another good reason to collect vintage is they don't come out with new stuff every month so it's easier to concentrate on finding a certain piece without having to spend your funds on a new toy every week.   Have fun!
