I think the Classic II gets a bad reputation because of what it could/should have been.
It could have been an updated, perhaps faster SE/30. If the SE/30 was a IIcx in a compact case, then the Classic II could have been a IIci, or an LCIII+ in a compact case. Instead it was more of an LCII in a compact case.
Taken alone, it probably is a fine little appliance (don't have one) but in comparison to what it should/could have been, it's quite a disappointment.
