Some things to keep in mind - these are probably obvious to you, but just in case....
* when comparison shopping, focus first on what prices the auction houses bring for similar cards e.g. if you have a T205 Joss, go check and see what price that card brought across each of the venues - its never apples to apples because of a myriad of factors, but its good data to have regardless
* contact the various auction houses asking if they'll give you data such as - how many auction catalogs they mail out, do they charge for auction catalogs, how many web hits do they get, etc - the more people looking at your stuff the better - i don't know whether they share this info, but it would likely help their cause if they did
* then look at consignment fee's
Some auction venues consistently do better than others even with the same type of material - you want a combination of highest price paid by bidders, highest number of bidders, and lowest net consignment dollars spent
Sounds like you're already down the right research path
