Ok, now I know you guys are getting tired of answering these type of questions from me, but I have been following the "you snooze you lose" addage. I am trying to decide between the 570 and 520 finally. I almost had in order:
RG550 $275 -- got sold
RG2027 $800 -- got sold
RG3120 $750 -- new got sold
RG620 $500 -- new got sold
Now I found a 520 for $450 no case. Wondering if I should go for it or do the 570 for $370, both new. My problem is I only have about $500 to spend. If money werent an object, I would already have a Jem in my possession. I started with $900 but things have come up since then.

I would greatly appreciate any suggestions!!
