There is one for sale here now for $250 I think. And it's from Yeticomm. They are great radios for SSB use and are not bad on AM. No they don't have that big Galaxy sound on AM, but they are clean and clear. Yes you can mod them to work well on AM I am sure, but they are or were built more for SSB and FM use it would seem to me from my own experience with using one for almost over a year in the mobile. And also used as a base radio too. Have had mine for almost 3 years I believe. Had a magnum 257hp before that and it worked well on AM and SSB, but the radio was just too damn fragile and rhey had issues. Throwing carrier, didn't like VSWR over 1.3:1, they started acting funny. Just weren't built with the same quality as the optima MK3. And the filter for SSB is a big plus!! It's really knocks down unwanted noise and enables you to pick up way more actual contacts. Did for me anyways. But those that are looking for big AM sound might as well stick to something like a cobra 29, or some of the older magnum radios such as the s45, S9, and so on. Or a Galaxy or connex radio.
Hey 338, didn't you say you were going to order a 2018 extreme mic for the optima mk3 you have?? If so, how did it work with the radio?? Not like it? You could always have the mods done to make it work well on AM. Per Yeticom LTD, it's possible. Don't see why it wouldn't be. But it would require some mods I am sure. Anyways.
Also remeber that there are still a few of these radios being sold by Yeticomm LTD. right now. I just posted a pic somewhere of the ad and website for them. They are $250 plus shipping I believe. Here is the ad again as of 1-31-17. Hope this helps someone!!
