Do you prefer PAM 104 or PAM 312

[Matrim604]

It seems Panerai is working very hard to become a "manufacture" company. They already have some interesting all in-house calibers in production, and seem to be slowly weeding out the ETA based calibers. I'm wondering if you, the Panerai fans, care if the movements in your watches are all-in-house, or one of their "tried tested and true" ETA based calibers that they can offer at a more reasonable price?

The reason i'm asking is I was looking at a PAM 312 the other day, and it's a beautiful watch, but it's list price is a fair bit higher than then PAM 104 with similar looks and functionality. Obviously with the PAM 312 you're getting an all in-house movement with a 3 day power reserve, which for many watch enthusiasts is great news, but Panerai has built it's current fanbase out of a reputation for ruggedness, reliability, and relatively reasonable cost.

Would you pay more for a PAM 312? or would you prefer a 104? (or another Marina based watched out of the Contemporary selection?)
