I'm doing some spring cleaning and have a Rigblaster Advantage that I've never really used - I tend to do portable operation and it's a bit too wide for my backpack.  It's pretty much brand new as a result.

These are about $290 at GPS Central https://www.gpscentral.ca/products/westmountainradio/rigblaster-advantage.html

I think that $200 would be fair.  Contact me at mbingley@gmail.com.
