Sadly there was another sale for only around $500. The description was minimal and the pictures only showed it booted as far as the self-test screen so I went with the higher one.
I suppose I get why someone would want a Lisa but with a nice setup going for about what I paid for my truck (which says more about my truck than it does the value of Lisas) it ain't happening. At least my ratty old truck can justify its existence to the Mrs. by being capable of hauling home the occasional load of compost from the garden center.
(Contrarywise, I don't get the TAM at all other than as an interesting monument to the unique flavor of insanity that Apple was infected with in the 1990's. It's tacky, overdone, and not particularly well engineered, barely one step over just taking a Power Mac 6500 and gluing Swarovski crystals all over it. But that's just my opinion.)
So, since you're obviously into the Lisa scene, do options/upgrades like that really *add* value? I ask because... for instance, up to a few years ago "your average" Mac collector would probably be stoked to find a Macintosh 128k that had been completely tricked out with memory upgrades, accelerator boards, SCSI cards, etc, but now it seems like the "collector" is more interested in finding and displaying unmolested examples, to the point that people are reversing 512k upgrades. (Which of course *sharply* curtails the actual functionality of the unit.)
I guess what I'm getting at is... does your "average" Lisa owner actually *want* to have "the most powerful Lisa on the block" and use it as an odd-shaped old Macintosh (since many of the "best" upgrades appear to be incompatible with the Lisa OS), or is the drive now to be able to put the thing on a pedestal and boot the Lisa Office System occasionally to show off the wonders of 1983 computing? It would seem that exotic third-party options would detract from the latter.
