Recommended Ethernet shield for the Arduino Mega 2560 R3

I will be purchasing the Mega 2560 R3 from Amazon

I've been doing a lot of surfing for info on a ethernet shield for the controller and it appears there are a few issues with installing a ethernet shield on the Mega 2560 R3.

I really don't want to jump thru a lot of hoops getting a shield to work with this controller. So, can anyone provide some insight on what to purchase etc. to minimize/eliminate my grief?
