maybe rabbitsemiconductor.com be at help. Its not cheap but simple
and easy.

Might as well blow our trumpet again...

It may not be the cheapest hardware combination but our standard
controller product includes a TCP/IP stack and has a built in
programming language both of which will cut your programming time
dramatically.
Have you considered how your PC will receive the data? We support
several ways of transferring data where you won't have to write any PC
code at all. (http server, ftp, email)

Woah, thanks for your replies!
Here are some additional specifics on the project so that you can
understand it more:
-I will be using an energy metering IC (ADE7752A,Analog Devices), this
will output a signal with frequency proportional to the energy measured.
This is the only input to my microcontroller.
-The microcontroller should display output on an LCD and also send the
values measured to the ethernet board.
-I plan on using a Z8 Encore! microcontroller since it is readily
available here in the Philippines (unlike Microchip-PIC which don't sell
products here.)
Some of the online embedded ethernet boards I am taking a look at are:
1) The Ethernet "MINI" by Fred Eady (www.edtp.com) $69
(By the way, he also posts articles on circuitcellar)
2) Spartan2E FPGA boards
-I have used them in my university, I have knowledge on VHDL although I
don't know if the board has the necessary TCP/IP drivers suite that I need
to be able to send messages on the network. (I don't have the time to code
the necessary TCP/IP related software.)
3) Olimex ENC28J60 ETHERNET CONTROLLER DEVELOPMENT BOARD (dontronics.com)
Can any of these be driven by the z8? or do I have to change my
microController to use them?
Please share your ideas on this one guys. Thanks again!

Cheap is relative. You could use a full blown small formfactor PC if
you're familiar with that environment. You could get a pico-itx
(10x7cm) motherboard or a cheaper mini-itx (17x17cm) motherboard with
an embedded ethernet cotroller. Or you could get a microcontroller
development kit like the Freescale M52233DEMO.

Get a copy of Circuit Cellar Ink magazine www.circuitcellar.com
You'll find tons of articles and ads for just what you're looking for.
good luck.

How much is "cheap"? I personally favor the Luminary 3S6965 evaluation
board, because it is more or less turnkey, includes a USB debug
interface on-board, and has a lot of generally useful stuff on it. It
costs US$69.95; probably more overseas. <http://www.luminarymicro.com/
products/lm3s6965_ethernet_evaluation_kit.html>
Olimex has a very wide variety of products too, but I haven't used any
of their Ethernet-capable boards. Many people in this NG use Olimex
products, myself included.
