I owned the 42mm 2201.50 for a few years before selling around 18 months ago in a consolidation move which I still kick myself for.
Prices on these, like many other watches, have climbed significantly so I can't see a reacquisition happening for me.
A very cool watch and a dam sight better looking than any other Planet Oceans that have followed since, I'd definitely hang onto it if I was you.
Looking back at these photos, I really wish that I'd kept it.
