I have received my screen. The seller shipped the day after I bought it, and it arrived within two days of shipping. I would suggest buying stuff from him.
Also, as for the screen itself. Though the pics show it having a brightness/contrast button, the LCD I received did not. It does not have an anti glare layer, and the quality is on par with other Chinese 3.5 inch LCDs. I tested it with a PS3 thus far; the text of the PS3's menus is perfectly readable, but the text of some in-game stuff is not as clear. Later on, once I get my batteries charged, I'll take some pics of the quality. Oh, and I can confirm that it works off of 8.4v.
