hi i'm buying my first HD TV and am really stuck between these three. i'm mainly going to be playing my ps3 and i hope to be setting up a home theater eventually and watching some blu rays. at first i was going to go with this "Sharp Aquos 40" 1080p LCD HDTV** (LC40E67U)" http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0770HDS0010124484&catid= but then someone told me the refresh rate is only 60hz and that it is going to make a big difference. so i also found this "Toshiba REGZA 40" 1080p 120Hz LCD HDTV** (40XV645U)" http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0770HDS0010122882&catid= and Insignia 42" 1080p 120Hz LCD HDTV** (NS-L42X-10A) http://www.bestbuy.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0926HDS0010119495&catid=24558 both the toshiba and insignia are 120hz but i'm really confused as to which one to go with. my price limit is $1000.00 and i'd appreciate any advice or help. i'm really confused with this 60hz vs 120hz as i hear from some people that it's a very noticeble difference and from others it's barely noticeable.
