1. I love my Olevia 1080i LCD. If you don't mind refurbished check out www.newegg.com for some amazing deals.
2. HD requires HDMI cables which are unbelievable overpriced at big box retailers. Best Buy (and the like) sell televisions at a low profit margin so they can sell you a $5 cable for $55. Think I'm kidding? Check out www.monoprice.com and don't ever overpay for cables again.
Go Devils (in HD)!
