Last night I adopted a neglected and abused Meade DS-90. For the price I was only concerned with the condition of the tube and optics, intending to replace everything else. Modest expectations were met. Barely.
Other than the OTA itself, this is a truly pitiful scope. The focuser is almost entirely plastic, and broken at all three flange screws (evidence, I surmised, of several escape attempts by the tube).
1/4 of the plastic rack teeth were broken off, and the finder had apparently ejected some parts as well, leaving an empty, useless 25mm tube.
The mount and tripod appear to be intact, though I'm hesitant to trust the plastic parts and hollow aluminum legs to support the substantial-in-comparison OTA. At some point I'll test it, if only to resell and recoup a few bucks on the renovation.
