I need Help . i am stuck between panny from bjs, model PT42PD3-P or akai from costco. Panny is costing me about $600 more than the akai . Is the Panny worth the extra $600. I looked at both of these several times on display, It seems like akai is little brighter. Any suggestions or comments will be helpfull. what would you do? Panny or akai?
