i have a 2001 camry, and i got my wood kit off ebay, as you said, the prices were very very different. here's mine (pics):
wood kit gen4&4.5 owners
here's what you have to look for:
1) try to get GENUINE TOYOTA OEM, im not sure about the 94's, but for the gen4's, toyota makes a dash wood trim, i myself would stay away from unheard companies, because you have no idea what the pieces are actually like, and im sure they won't send you a sample piece.
2) if your looking at wood, make sure it says, REAL WOOD. the title may say like "burlwood" but in small words inside the description it may say like.. "imitation wood" or some garbage.
it really is a great addition to the car, it transforms the interior a great deal. good luck
