If you're looking for something to rebuild, then you're partially on the right track with "enough value to be worthwhile". My opinion will probably a bit different on the model of saw though. Look for something new and common enough that parts are still readily available from OEM and aftermarket sources. Doing it this way allows you to concentrate on the saw, rather than finding obsolete parts from one or two sources.
