LL Bean indeed has some respectable not-quite-military A2 jackets in its past. At one time Golden Bear made them in the US from a very heavy goatskin, in both one-piece back and three-piece configurations. My only beef with the Beans is their enormously generous sizing: their old Mediums were about a 46 in military sizing. Their longs are clearly intended for Kobe Bryant-- I have a Bean XLT that has a 32 inch hem-to-collar measurement!
One other decent value-priced A2 you might find on ePrey is an older Banana Republic with the crested label. These were often Korean made, usually a hearty sheepskin with striations, and seem to age really well, patinating into a terrific cream-and-mahogany mottled hue (see photo from a recent eBay auction, not mine). The pockets are oversize, but otherwise these are respectable jackets, often for $50 or so.

I've never really understood why people like these versions. They look like the baggy, pre-distressed thing Michael Landon wore in that creepy show Highway to Heaven.
