I own 2 ICBM's - both like new with all original manuals and packaging. Check my history on Audiogon - I was about to list one of my units there until I ran accross your post.
If you are still interested - drop me an email. I have a current Audiogon Blue Book subscription for values and pricing.
Current Audiogon Blue Book Average for the ICBM is $190.00. My units are like new p this one with very light use. I'd sell for Blue Book and pay for UPS Ground shipping to a US address. This one is a 9/10 on the Audiogon scale.
