The venerable 16550 is an 8250-compatible, so that would be $4.47 from Digikey, plus another couple of bucks for a PLCC-to-DIP adaptor from wherever. DIP versions are also available at a similar price, but from less-reliable sources. I haven't put the two datasheets side-by-side to check, but if the 16550 isn't actually directly pin-compatible with the 8250 (which I expect it probably is) then it'll certainly be close enough that a few bodge wires on that adaptor board will be all that's needed. We're not trying to install a Threadripper into a 286 socket or anything like that.
