Panerai newbie questions

[DocBotanus]

I started getting into replicas last year, and finally got my first- a last generation SeaDweller- from Josh. I actually started out looking for a Sub to make into a "Bond" but that's another story.

As you all know, this is an addiction, and I started turning my eye towards other divers, like gen vintage Omegas, but I started to fall prey to the rugged, simple Panerai.And you know where that leads...

As a newbie, I am trying to educate myself by reading the forum, but any help would be appreciated. A couple questions-

1)Any recommendations for a particular site(or posts here) or book that would give me a good basic knowledge of the Panerai?

2)Any particulars to look for in a rep? I had tried to arm myself with knowledge when buying my Faulex; the SD I ended up with is (I believe) very nice, but it was also $300. I was looking at some reviews of other Rolex reps here, and found some very nice ones for $100. In fact, looking at the watchesla.com adverts on this site, I saw some SD replicas that look a lot like the one I bought. I'm not worried about what I spent-what's done is done- but can the Panerai reps on this (or other dealer's sites) be anything good at $70?

Thanks for the advice, and wish me luck in my new addiction!
