DO NOT BUY ANYTHING USED IF YOU #1 DONT KNOW OR TRUST THE PERSON,  PERSONALLY  AND WITH THE AGREEMENT IF SOMETHING IS WRONG IT WILL BE TAKEN CARE OF!!!!!!   i don't fly turbines let alone would i buy a used !!!!!! i'm scared to buy a used gasser!!! da.dle ect... you never know what the original user mind set is in what they interpret (ie) just broke in, runs great, run on bench only, and the favorite, never run still in the box!!!!! the bottom line is when you buy used there is always a reason!!! you take you chances and repair it if you have to!!!!!! a lot here on rcu are legitimate!!! i have sold here too!!! mostly aircraft and i will and still stand behind what i have sold!!!!  if you want some kind of personal guarantee!!! buy new!!!! that is all there is to that!!! sorry!!! to be so blunt but that is just how it is in today's world!!!!! at least for me it is!!!!
