[Milsurplus] Re: Milsurplus Digest, Vol 36, Issue 36

[Greg Mijal]

Mike:

$700 is more than twice the price that those converters  typically go for on 
Ebay.  If you keep watching  you should be able to get one for around $300. 
I've sold two of them on Ebay in the last two years.  Both went for around 
the $$$ I mentioned
As far as I know, hardly anyone parts with their converter locally due to 
the magic those things do to a R 390A or SP 600.  They really are deluxe.
Good luck
