I agree, that MOSFET are preferable in terms of efficiency. But Linspire has been asking explicitely for a bipolar transistor circuit. In those cases, where the supply current doesn't vary too much, the additional base current can be almost neglected with a correctly dimensioned circuit.
Yap, I have tried search logic level mosfet in my local online shopping which doesn't sell it or maybe (I really no idea these MOSFET stuff)

What'd you mean by correctly dimensioned circuit ?

I have used multisim ver.10; I cant find anything regarding about logic level MOSFET, and your model (KMoffett) isnt at there at all.
