The problem with Radiomir is that it's missing the crown protection which is kinda a landmark for Panerai. So, I'd say first get a Luminor, then get a Radiomir. :D
I am seriously considering a 210 as it's half the price of the 1334/1335 models and has a non gradient dial - less is more. The new ones are beautiful but still too over the top dials for my taste relating to Pams. And, as one poster wrote it, Panerai's a are a great 2nd hand deal. :)
