Why not try out CigarBid? Here is a nice 5-pack:

This 5-pack is regularly $25.00, so you can't beat the price. If this is not the size you want, just wait around and more will come in.

I am just providing you this as an alternative to doing a box split.

Also, you should try the Newbie Sampler. This would get you the trust and approval you would need in order to get someone to do a box split with you. I'm not saying that someone WON'T do one with you, only that it would be easier after that.
