My thought for the price is that I paid about $350 all told from Ambient Weather. While it has been used, it is for all intents and purposes, almost new.
Also, that is why I said I would be happy to entertain offers!
As for the USB, I never had any problems at all. I ran it on both Windows Vista-32 and Windows 7-64. The weatherlink software worked well, and it was easy to have it upload to a website, CWOP, and WU.
Please let me know if you have any other questions, or would like to make an offer. My email is firstname.lastname@example.org
