TBS ships their LR with water in the box. essentially it's underwater all the time. No other place i know of does this practice. Everywhere else ships in wet newspaper. If you want fully cured LR with a pretty good guarantee of no cycle then id say your best chance is to wait until someone local decides to sell off some LR. that's what the classifieds are for!
or if you're a handy man with some time on your hands, you can MAKE your own LR. that way you can get custom shapes to your own liking, while spending about a third of the cash. plus it's super easy on the environment. GARF had a page on how to make it... lets see if i can find it...
