I wouldn't buy any display unless the seller could guarantee compatibility with the raspberry pi.

Many sellers on eBay/Aliexpress/etc will mark screens as "Pi Compatible" but won't offer any support/software to get the screen working. I would only buy a screen from a reputable UK Pi reseller (even if that meant spending a bit more money)

I bought several cheap ili9341 controller based SPI LCDs from different sellers in China (via aliexpress.com) and they work fine with Raspberry PI, even as dual screens:

My LCDs are all 2.2", but you can get as 2.8" as well which may or may not qualify for your 3" requirement.
