i hope you find one, i got mine from ebay, a 3" with air, reserve tank, hooka, everything, yes the enigine needed a little love but wasnt too bad....
i love it, its all the dredge i need, and its fun too
glug glug
the size is right, and really its plenty of dredge for most applications
i wouldnt recommend a smaller one, but the 3" is right for me
