Advice on motor mover options

gadgetpaul

Hi All, 

we are relatively new to caravaning this being our second year after being under canvas for years, we've now decided however to purchase a motor mover as we often struggle to get into our caravan storage space with only a foot spare either side and an awkward
 motor home  parked making it hard to reverse. my question is I've read tech info and reviews and compared prices but now even more confused as to which one to choose for my swift charisma 550 single axle.. Could anyone help ?

budget £900 

manual or auto ? Which is better 

thanks Paul
