I find that not to be true here - I've sold many overhauled low-end Centurions, Univegas, etc and made my $100 and then some. Demand is demand, and a clean, pretty, well-presented bike will get sold for a good profit.
I do avoid dept store bikes - unless I get them for next to nothing AND I can use the tires/tubes, grips, etc. I'll never overhaul one and resell it, but I will strip it for usable parts and toss out what I don't need - if the price is right.
