Ethernet Blaster Question

DigiKey says it is obsolete, no longer manufactured or available. Mouser says it has one left in stock.

Personally, I use the TerASIC USB Blaster:

it is equivalent to the Intel/Altera USB BlasterII at a much lower cost.

Or for even cheaper:

I have one of these also and it works just fine.
