I have the APQS Millennium and love it. I prevously owned 2 HQ16's and they were also nice, but I love the Milly much more!
APQS is wonderful to work with, support is excellent and the warranty is the best in the business. After I bought mine, I went to Iowa and did the factory tour as well as taking the maintenance class, and the folks there are just wonderful.
p.s. I am not a dealer, just a very happy customer!
