But if you sold frags, you'd more than recover that $500 with those extra inches.
Also, often, when paying more, you get greater reliability and warranty. Not always, but often. I expect that my 8 year old Tunze will still be going long after my WP60 dies.
Come on Brad do you really think a hobbyist can "recover" money by selling frags? Whatever comes out of the tank goes in with added interest
