you can find them cheaper than that if your in the us
Baja 5B rtr is about 950. Baja SS kit is around 900. Baja 5T is around 1300. these are including shipping from DDM to conus.
now which one is the tricky part. you will need to toss a bit more money on a new one to make it a bit more durable regardless of which one you buy.
new radio system for any of them. buy a 2.4 radio like the Futaba 3PM or Nomadio React and now worry about radio issues again. you ll want a motor kill switch to kill the motor in the event of low battery, major glitch, rip the rx batts out ect... it kills the motor, motor isnt running car can't run away, Great 40.00 investment after a 2.4 radio system.
from there i depends alot on what you want to do and how you drive. easy and smooth like an rcer, or wild and crazy like you were in it driving for your life? lol
you can get some Very nice units in various forms of upgrades for 900 to 2000 or a bit more depending. infact, i have my mean green build i will be cleaning up and putting up for sale to buy a 5T. its pretty highly modified and wont be the cheapest for sale, nor the most expensive one, but will be in very good condition and ready to use with a radio system.
