Accutron (Bulova) Spaceview 214

Which year would Accutron fans recommend getting if you were only to get one Accutron in the Alpha case? The way I understand it is that if I buy an M0 (1960), it means that "if the watch was purchased originally in 1960," the watch was definitely converted into a Spaceview by a jewelery store or dealer back in the 1960's, since the Spaceview was not produced by Bulova until 1961. If I buy an M1 (1961), it means that "if the watch was purchased originally in 1961," the watch was either converted into a Spaceview by a jewelery store or dealer back in the 1960's, or it could have come directly from Bulova as a Spaceview. I know there is no way to tell, and that is OK. My question to everyone is which year, in your opinion, do you feel is "more collectible" or "wanted" more for this watch. Assume the condition of the 2 watches is the same between the M0 and the M1, since this is the most important thing to collectors.

Thanks,

John
