Do you have a thread going so that I can follow along, I also have considered the 170 and am curious how it would on out.Welcome!
I am in a similar place as you, maybe just a few weeks ahead. I have my RedSea Reefer 170 being delivered next week and am currently researching the last 6 years or advancements in all the other necessary equipment and having problems making decisions between all of the options. Will follow along here and see what you come up with as well.
