The ENC28J60 Ethernet Module utilizes the new Microchip ENC28J60 Stand-Alone Ethernet Controller IC featuring a host of features to handle most of the network protocol requirements. The board connects directly to most microcontrollers with a standard SPI interface with a transfer speed of up to 20MHz.
• ENC28J60 Ethernet chips, SOP28 package
• SPI Interface
• 1×10 connector, can be easily mounted with the MCU
• Built-in isolation transformer RJ45 connectors HR911102A
• Power LED
• Single Supply: +3.3 V
• 25Mhz Crystal

I'll give it a thumbs up, because i just can't complain about it.
Good build, simple conection. I'm using it in a home automation project with a Mega running a custom firmata made to work with it tcp/ip.
Unlike other ethernet shields, it does a little more code, so a little more programing space, but it works never the less.
Great price for it's capabilities, and really worth it if u need to network your arduino, mega or otherwise.
Ps: as i remember, the whole custom firmata code might not fit onto a uno, or was it a leonardo... Can't remeber.
