Glad you liked the SuperOcean Arthur1
Interesting choices. I went through a Zenith phase once - but I couldnt make my mind up on a model to go for. Now im completely off them :-)
For Pams, everything said above is true. The AR is shocking and there are incorrect features as compared to the gen, which might make you think twice if getting a rep close as possible to the gen is your thing (it is for most of us!). The DSN is the best choice, but I see you are looking to pay at the lower end. In this case, why not try out the lefty pam from the link? - you may love it. You'll get an idea of what your money can buy and might want to upgrade in the future.
try it out and see - good luck
as for me, ive been deciding for months what my next rep should be... It'll either be a SINN U1 (eta), DSN PAM 111, or EBEL BTR 137 (I've trialled the quartz - nows the time for the upgrade to A7750)
