I just made a recomendation on what I would use, I thought mabey he forgot about iwaki pumps, he never mentioned any concerns of price so I thought I would recomend the best pump for the application, Ive used and serviced both brands of pump and would never buy a mak4 or any mak pump again, I look at pumps like tires on a car, they hold the power of life in the palm of their hand, I pick quieter extended life. Just my personal prefrence, more expensive? yes, worth it? yes.
In my eyes....
