Seriously, for PAM reps - especially base - I don't think you can go wrong with a modded watch by Davidsen, The Prince, Angus, etc. Almost perfect out of the box, because IMO - you'll love it at first and then start nit-picking. First comes the cannon pin fix, then superlume, next thing you know you are at that $500 mark and have been without it as it sits on a modders workbench for a week or two.
I'm in love with my 112 from DSN. I've also owned his 005 and 113 at one time or anther. Figure out if you want SS or Ti, then if you like the subdail w/ seconds or not. Then pull the trigger on a 000, 005, 112, 111, 176, 177, etc.
