Would a Bass VI do it for you? The new Squier VI is $350, the Fender Pawn Shop VI is $800, the Eastwood Sidejack VI is (I think) $700, and there are one or more models from Schecter, Rondo/Agile, and probably others. Oh yeah, Ibanez has a new model this year too. A Bass VI is essentially a 30 inch scale guitar tuned an octave lower than a traditional guitar. So the bottom EADG strings are tuned just like a traditional bass.
