I'm just CURIOUS how long it would take someone to make a filter kit, from getting the first wrench, removing old filters, design work, multiple set up, turning the parts, source multiple parts, assembly, testing, corrections, install, more tests, ect, ect, ect,. I see a EASY 10 HR, from picking up the FIRST wrench to putting the LAST wrench away and picking up the end of project BEER, If this project JUST took a total of 10 hr, at the new price of $200, that is ONLY $20 an hour, the old price of $160 means it is $16 an hour, I would like to KNOW where I can get ANY MACHINE work done for $20 ph let alone $16 ph, now try R&D or PHOTOTYPE work for a VERY SMALL comsumer base, I can not even imagine that cost
