Is there much or any changes to the panel quality between revision 01 to 02? I was about to lay out $600 for a new monitor but that is very hard to justify for basic photo editing and general web use..I stayed away from dell due to all the horror stories I've read about returns etc. but it seems that things have improved....Thoughts on this panel now? Or just go for the NEC PA231W and assume a panel with little to no lightbleed and good uniformity?Thanks,Bob
