I was just trying to give a technical response to your non technical whine.
I resent that it was a very technical whine.
It is you who are the moral degenerate cheapskate happy to live off the back of others.
As to ebay arduino boards, buy from vendors that have good feedback and have completed large numbers of transactions.
Well that is your advice.
I have not always found that to be a reliable indicator of worth from an ebay supplier. In fact one of the worst supplier has one of those medallion logos saying what a good supplier they are and he ripped me off to the tune of £500.
