FWIW. Because 'I' am amongst those for whom steel bicycles frames are generally worth considering ...
AND, because the MIDAS frame appears to be well crafted ...
- that actually looks like a pretty nice fork
If I were 5'11", or taller, then 'I' would not have qualms about buying the bike for anything up to $200US because a good, vintage steel frame is easily worth that much, IMO (to me!?!)... possibly more ... definitely, for less.
- a very GOOD off-the-peg steel Road frame could cost you $800-to-$2000+, new ...
- figure $200-to-$500+ for a slightly more modest, contemporary steel frame/fork
- However, be advised that there are others who wouldn't pay $50 for a used bike of that vintage ... and, they may be wiser!
The bike needs SOME maintenance and/or having some of the components updated ...
- excluding tires-and-tubes AND (possibly) a different saddle (due to differences in rider preferences), for the cost of the bike + ~$200* + a small amount of DIY effort, you could have a VERY contemporary, nice riding bike ...
* $200 will buy you a pair of 10-speed Campagnolo shifters (on eBay) + a new 7-speed SunRace Freewheel + (if needed) a suitable Shimano rear derailleur -- THAT combination will work together.
- downtube cable stops which used to be included with shifters are an 'extra' which you will need to source
IMO, after "updating" (of course, the bike could be provisionally ridden as-is after minimal, requisite maintenance), you would need to spend well over $1000 to get a comparably equipped bike from a shop ...
Of course, you could end up spending MORE than $200 on 'extra; components ...
BTW. There are those who will say that once you are in the $400+ range that you should be looking at a NOS bike from a shop ...
BUT, those bikes (sub-$800 MSRP) will generally have woefully low-end (but, good if not neglected) components & questionable (IMO) indexed shifters which will be 'okay' for Flatlanders or people who never venture out of their neighborhoods or who limit their riding to bike paths (there is NOTHING wrong with limiting one's riding to those venues, BTW -- the bike should-and-only-needs-to fit the individual rider's needs).
