If you can get L82 at $250 dollars, that is a very good price.
Make sure they are L82 as the can easily be missed ID with other plecos such as L201, Hypancistrus contradens, LDA31 and others.
I suggest to do a little research on the specie in order to be prepare once they become available at your LFS.
I hope they become cheaper and more available to the hobby, as very little is known about these amazing species.
