Wrestling Cards - A Price Guide is needed

If you've been shopping with me for awhile, then you know I've had a lot more wrestling cards in my store than the regular 4 major sportscards.  This is due to the enormous response I got when I first started listing wrestling singles.  I now find that a price guide is really necessary for all the various different sets and types of inserts and cards that exist.  I've got the Tuff Stuff free guide and I've seen the Beckett attempt in their new magazine but I don't think either one does the Wrestling card market any justice.  I've been labeling some cards appropriately as rookie cards and collectors seem to respond well to this.  Why isn't there a better guide for this??  I was thinking of trying to do this myself but I'm no expert, I just know what I sell the cards for...  Any thoughts would be appreciated...  David
