Best scanner buy

[2009joe]

hello i am thinking of selling off my scanner which works great and it has lifetime updates and its got the all cars on it unlike the new autel ones where you have to pay if you want to scann more cars. well the one i bought a right few years ago but well looked after is a autel maxidiag elite md802 all systems but unfornatullly why im getting rid of it as it dont cover dpf on it as with my next to no driving i might have to put my car on the scanner to do a dpf regen itself to keep it in good shape  i have  a couple in mine but one is a tad expensive tbh never the less worth the money as if well looked after should last a long time  the scanners i am half intrested in are 

(1) autel md808 pro 

(2) Mac ET R8 Scantool
