This is the best re-man on the market. We began re-manufacturting years before any other compnay in the USA so we have learned a few things. You can choose the option of 3 or 7 year warranty VS the industry standard of 1 year. Only top grade, premium parts are used. 
There is an addition $600 added at checkout for the refundable core. 
Current build time is 6-8 weeks
