[DViper2399]

I was looking at 2 sets, I now have a 42" Panasonic LCD but it's only 720p & 1080i....so I want to buy a 1080P tomorrow(Thursday). I was a BJ's looking at the Vizio 47" LCD 1080P (Model# GV47LF) read alota good reviews on it looked decent at store display....but next to it I noticed a Phillips that picture to be honest looked alot better & I could spare the extra $200 for a better picture!(Model# 47PF9441) it read & claim's to be 1080p but when looked on-line I read that it actually only accepts up to 1080i & then up-converts to 1080p thus really ever only being 1080i(30fps) no 1080p or 60fps what's the deal & what set should I go with I definatly need 1080p not 1080i/720p cause I already have a nice set for them, I want 1080p for my Blu-ray's.....ASAP Help is much appriciated, Thanks
