Looks like that Lisa with the 3.5" Art Dept. floppies is being sold by MJ Posner, and he's lowered the price to a more reasonable value. Looking again at the description of all the included stuff, I think it's worth getting if anyone here is looking for a good chunk of Lisa items. (So I'm adding a reply to update my original assessment from above.)
Just be sure you're able to do the soldering needed to recapping the power supply. (That's not actually hard since it's all through-hole.) Likely a full set of capacitors would be under $50 and would take an hour or two depending on your soldering skills.
It may be possible the Widget is completely toast, he mentions a connector failure, but it could be much worse. Sadly Widgets aren't always easy to fix or as reliable as ProFiles.
It could be as simple as blowing the dust out of it and cleaning the edge connectors, or reseating the large square chip in its socket (which is known to gather dirt under it), or freeing the spindle motor by hand, or fixing the gap in the clamp brake, which are very easy fixes. Or it could be needing to replace some of the boards on the Widget, or catastrophically, the optical track sensor has fallen off internally. So that's an unknown.
Most likely, unless you're trying to recover whatever data may be on that Widget (which I'd encourage you to do - never know what goodies you'll find not on the included floppies), you're better off with an Aphid/X/ProFile/IDE:File, (and a FloppyEmu with the switch option.) So factor in that you'd likely spend another $100-$500 to make this Lisa fly.
But all the included original items (manuals, disks, etc. keyboard with pull out cheat-sheets, Lisa 1 Mouse, ) make it worth it, and especially since this is a 2/10 and not a 2/5, there's no leaky NiCADs to have caused huge damage to the I/O board, so it's probably a decent price for all the included extras.
I already have 4 Lisas (all of them needing some repairs, mostly to the analog boards and all but two needing power supply recapping) and am paying off my toy budget credit card, so not going to buy this myself, but in case someone here wants a 2nd Lisa or even first Lisa, it's not a bad choice.
