Same here. Case prices are just ridiculous. Get AppleCare plus and call it a day.
I have to agree with the next person - cases are dirt cheap. I don't know how some people have spent 100's on cases and screen protectors. Hopefully none of you purchase cases at walmart or radioshack for $20-40. You know Dollar Tree often sells the exact griffin and speck cases for iphone 4 that radioshack does, right? I bought 20 griffin cases at $1 each. Or just go the ebay route. $1-$5 with free shipping. Or 2 packs of screen protectors for $0.99 free shipping.
The most I've ever paid for a case was $12 for an otterbox defender (which was a present to my friend).
I actually just bought an arachnophobia case for $11 for my bad esn iphone 4 (so signal loss doesn't matter to me).
I will agree that some cases lessen the feel of the phone, and some screen protectors just ruin everything. But I have an awesome screen protector right now that I paid $0.99 for, and it doesn't change the feel or look at all.
