Base is, imo, the best choice since it is the closest to the original PAM...manual winding, sandwich dial, non-hacking. Most ristis will eventually get a Base at one point or another. You may also want to scour the pre-own market for a 1 or 2. Anyway, you can't go wrong with either one. 88 is a classic (the PAM that got me started).
The three models you listed are hard to come by. I have not heard of many shipments for these three models this year as Panerai seemed to be pushing the new manifactura models more to the ADs this year. Good luck with your search.
