Milwaukee Mitre Saw 6955-20 & 6955-80, differences

Thanks in advance for the help. Looking to purchase a 12” Milwaukee compound mitre saw and see models 6955-20 and 6955-80 out there but can’t find any comparison between the two. 
 

The -20 seems to retail at a higher price point but unsure of where the variance is. 
 

Any clarification is appreciated, guys. 

-20 is new and -80 is factory reconditioned.  Milwaukees number system first 4 numbers are tool model the 5th number is either a 2 or 8 which indicates new or recon, and the 6th number indicates how many batteries come with it.

Thanks, @Biggie! Ended up ordering the reconditioned model. Appreciate the info.
