Jarrod,
If you only want to open 1 pack, why not buy a pack from Steve Hart and leave the wax tray sealed? He sells them for $12 each and you would come out much better. The value in the wax tray is the fact that it is rare, not so much that the packs haven't been searched. Once you bust the wax tray, it looses it's value and the individual packs aren't worth any more than any other unopened '79 Topps pack.
And not trying to bust your bubble, but if you think wax trays can't be resealed, you need to read my post in this thread...
