Anyone looking for a cheap ETek EB-85A with latest firmware should take a look here: http://www.ohararp.com/products.html
Ryan is selling them for US$ 55.00 a piece, a real bargain compared to what others (Sparkfun: US$ 99.95) are asking for these. Firmware version is: 1.85 0008, that should be the latest firmware.
Payments on their website can only be done by credit card. They accept PayPal payments at firstname.lastname@example.org
I am not related to this company, but I know the owner for some time now!
