You can either check for a local dealer, or you can contact Perrotta Consulting, as they advertise here on Audiogon. I believe my friend with the Revel Salon 2 speakers, bought his Lamm M2.2 from them as a demo pair and saved a fair amount of money.

You might want to see if they have another demo pair. (FYI, Lamm amps are incredibly well made and will last you a lifetime, based on what I have read, heard and seen. I have owned mine for five years, and I am the second owner, and they have given me no trouble. Neither of my friends who own Lamm amps have any had any trouble either, so I would have no qualms about buying a demo pair myself.)
Good Luck!
PS FYI, they use one 6922 tube in each amp. This makes tube rolling both easy and relatively cheap. I recommend swapping out the stock Sovtek and replacing it with some sort of NOS tube. An Amperex Orange Globe 6DJ8, (the same thing as a 6922), is relatively cheap ($80 /pair) and sounds great. (In fact they are very close, sonically speaking, to the Amperex Pinched Waist 6922 tubes that my friend and I both use, and they are much cheaper. If you want the best, you can go for the Pinched Waist versions, but they tend to run several hundred dollars a pair.)
