Is it worth getting monitor RTA-15TLs for $50?

Someone just wants to get rid of his 15ts, description indicated one works other doesn't. Cabs, grills look decent. I really don't need another project (working on an 8t at the moment), but thinking of getting. I can deal with crossover & tweeter upgrades and magnet shifts, wondering whether it is better to get and part out or to upgrade and sell. These are less desirable than others I believe, not sure what the market would bare?

Comments appreciated.
