I bought mine off eBay, just a set of lucky circumstances - young seller, little experience, incorrect category, etc. Do a search for Bose in all categories. You'll get a lot of useless stuff, but tha's where you'll find your Compact. You can also set up a WANTED to buy item on eBay and they will let you know when something like that becomes available.
If you have any contacts at retailers that sell Compacts, ask them to keep their eyes open for a return. Lastly, and very rare, the Bose Outlet stores might just carry a refurb. That is the only L1 product they carry - rarely.
