I'd definitely pick it up, I finally got one after years and years of ho-humming over it and am quite enamored of it.
Like Byrd said, it's the SE/30's cousin, but I'm not quite sure which one is more well off. The SE/30 has much more room for Memory expansion, but the IIsi has quite a lot more slot expansion options available, including every SE/30 PDS card with the exception of a few that can't handle its faster CPU/Bus, but with NuBus expansion available as well.
I'd look at it as the bottom portion of a lot better CRT than the SE/30's 9" periscope. The, fitted to the case, 12" Monitor has more pixels in Grayscale than the SE/30 has in B&W, the fitted 12" RGB Monitor throws Color into the mix and the Macintosh Portrait Display sitting on top of it is just the cat's meow, if only in gorgeous grayscale.
A SCSI HDD can't be all that hard to source, even if you have to buy another II to Quadra era Mac to share it with to get one!
