Liquid $70 more than what pump? the closest pump to the gri 520 would be the iwaki 70 md rlt and they're the same price (the GRI runs almost 100 watts less though). I never used a GRI pump but from the advice I got here and on RC I think it's worth it....maybe
I just don't want to have to upgrade anything once I buy it so i am buying the best, first. It will same me more money in the long run ....
