SUPER PORTABLE ATU
I've always been fairly happy with my LDG Z100PLUS and have never seen it as a great hardship lugging it around with me when working outdoors. It is, after all, quite compact and runs off internal batteries. But it does have a steel case and those 8 batteries do add to the weight when you're walking up hill.
So when I bought an IC-705 I started to see more and more posts about the MAT Tuner and the ICOM AH-705 Tuner. Neither of these appealed to me because the MAT-705 had some quality issues and the AH-705 is just too focused on the IC-705 (and it's too big). I prefer a tuner that I can use with a variety of QRP radios.
So then I recalled just how amazing the ATU was in my Elecraft KX3 and so I decided to investigate the Elecraft T1A tuner. The unit is about the same price as the KX3's internal ATU so although I wasn't exactly thrilled with the cost, neither was I surprised.
