Does anyone recall or know what the K4D price was if you ordered back in May of 2019? For those who have received their K4 on the East Coast, what was the shipping cost for just a K4D? I'm on the fence here as to whether or not I should invest in the K4. I'm also considering the ATU but I already have the KAT500. I'm not getting any younger. :-) Tnx es 73, Dave N8AG
