I don't know why ICs like ENC28J60 or W5100 / W5200 / W7100 should be much more than 6 Euro !
Where do you order?
I'm working indirectly for WIZnet, so I'm not
independent. I'm prejudiced.
but, ! both chips cost less or around 6 Euro, for small quantities !.

See here what is possible on a small MCU + W5200:http://www.dacomwest.de/eng/e_new_evb90363web.htm
(open source Web server with Sensors and graphical 3D I/F, Java-Script, DHCP and SMB)
It's stable for weeks, month, and years. Sorry Microchip, I don't believe ENC28J60 can do that.
And this W7100 (4in1) is a 5 to 6 Euro IC (8051 + engine like W5200) in one silicon chip.
The W5200 is a 3 to 4 Euro chip (3in1: HW TCP/IP + MAC + PHY)

I like Microchip and Atmel the same in MCU, and I just wanted to point out possibilities and correct price ranges when it comes to Ethernet.
