I've learned the hard way, but my advice: set a budget, outline your pickup goals, and proceed with purpose.

The expos can be overwhelming, with vendor after vendor and beautiful new morph after morph. My fiance and me get overwhelmed and lose sight of what fits into our collection and plans.

Our policy: Walk the show, collect thoughts, and go to lunch. Outline our options, think about it, and go back and buy.

Just my opinion :-) I would say there are two stages, $100-300 and $600-900. I don't see much inbetween. Figure out what works for your budget :-)
