Guys,
Check this link from KRV:
http://www.kvraudio.com/news/sanford-sound-design-updates-free-sanford-reverb-to-v2-1-for-64-bit-windows-31482 Bummer that the home page doesn't have any contact info, because would like to thank Sanford for what he has offered over the years without having to dive through the mire of Facebook crap.
Don't know the details back then, but Leslie was bashed over his reverb unit on KRV and think this was enough to draw him out of the commercial field. I paid for the commercial version years ago, and it still stands in there among the best. Benefit for now is this gem is free and also 64 bit. 32 bit version is included and byte for byte, same as the original.
Sanford also did an excellent arp plug and his 32 bit Cobalt synth, which is still cool. Website says he is working on updates and will release when ready.
Sanford delay is there free also, but for my liking, misses out on a mod function. Still very basic and functional.
The reverb unit is excellent. Don't regret having paid for it before it is free. Would advise anyone to get it while you can.
John
