While I agree that Jim is doing fantastic things and that supporting him
however you can is a great idea $18 / eeprom is not cheap especially
when you consider that it could be the single most expensive parts of
some of the refurbished labs (excluding the server and network).
I spent the money for a Eprom programmer and an Eraser so I am able to
take advantage used EPROMs from ebay ($1 for used 27C256) as well as
this site:

That being said, for the number of EPROMS I have programmed, buying them
from Jim would have been the cheaper route.
However, a number of Network cards can flash eeproms. The 3c905C is one
of those cards and is readily available pretty cheap:

I have purchased several from vfxweb and for some of them I got lucky
and received cards with PXE built in.
When it comes to remote booting I look for:
1) PXE support for the onboard NIC
2) PXE on the card (these are cheap whn you find them)
Preprogrammed EEProms are for specific NICs (pci ids) and when you get
into programming them yourself via a NIC you should have more time than
money...
