I'm sure you can bitch to Dell enough to get them to replace it, they supposedly hate when you're not satisfied, lol
Rebates..I'm not sure anymore. When I bought it, it listed for $1100 on their site, and I picked it up for $800 from Dell Small Business with a 3 year warranty. Now that it's $800ish on Dell's site now, i'm not sure if they'll go lower if you haggle a bit with them. Coupons sometimes come around too though.
It's a beautiful screen also, I love mine, now that I have my Truelife WUXGA on my M170 I kinda wish the 2405 was glossy, but it's a badass LCD either way.
