New HW motors poll

[adz600]

hi all just starting No Toy Robotics new heavy weight most the parts are all ready assembled apart from the drive motors, been thinking on this for a long time but still undecided. They need pushing power, durability, ease of replacement, ease of drive system mounting single or double stage boxes both are not an issue I have two main motors in mind

bosch 750
amplflow e30 400
NPC T74 Motor (because I know of two around)
