I see you just joined and already bought some stuff but I still want to point to some cheaper stuff not really/completely compatible with arduino.
this is a thai company producing many types of boards like:

and sell a RS232 arduino with ENC28J60 for $17 and mini boards also available via:
on request one can order their products via:
บริษัท อีเลคทรอนิคส์ ซอร์ซ จำกัด search for ETT

pitty the arduino system does not run on the 32 and i'm not smart enough/to old to port it.
Succes with your new project,
Erik
