[GreenKeys] RS-232 - Current loop converters available

[Alf Fisher]

Hi Jerry,
If you think that is a bit high, I thought you might like to know that these 
units appear to be available from no less than 6 suppliers on ebay asking a 
range of prices.

The highest one is asking $250.00

73,
Alf

Thanks Jerry. $43 sounds a bit high to me.
