Difference between 2014 and 2015 Hustler Fastrak SDs

Hi all,



I'm about to purchase a Fastrak SD with a 60 inch deck and have a choice of a new 2014 or 2015 model. The 2014 is around $500 cheaper and I'm thinking of going for that unless the 2015 is substantially better.



Any advice/views?



Thanks in advance,



Gavin.
