My circuit uses parts the OP probably already has on hand.
As soon as I get a finalised schematic (I'm sure it'll happen eventually

The motor's current does not flow through resistors so their size is probably fine.
Bear in mind that the high gain transistors are about three to four times as expensive as normal transistors.It appears that the schematic is slowly creeping back in the direction of my original schematic, with the addition of the high-gain transistors. I'll check out the link you gave me in a sec.

this circuit will not work.
Your SIM program shows that some circuits will work if you spend hours testing transistors to select the "typical" or best ones.
You cannot buy "typical" transistors anywhere. You get good ones and not so good ones. All the transistors will meet the minimum spec's on the datasheet that the SIM program knows nothing about.
So if you want every circuit you make to work properly then design it using minimum spec's. Then this circuit will not work.
The software simulation gives a good idea of how the circuit will work, but either way I'll be going with the suggestion hero put forth, and modifying it with schottky diodes on the ground side to fit the theory I've been discussing with marcbarker.
Only if the transistors you use have the same spec's as the simulator's transistors that might be wrong or are "typical".The software simulation gives a good idea of how the circuit will work
So you should design circuits using minimum spec's then every circuit you make with passing transistors will work perfectly.
