Do such things exist? I wouldn't mind paying $100 to $200 for one, but it must:
- Have a very fast spin-up to ready time (less than one second)
- Have an even faster dismount time (say, half second)
- Can go from dead stop to laying down bits in two seconds or less
- Can be instantly abortable and resettable regardless of current operational state
Does anyone know of such an animal?
