Kmart at Garden City has quite a selection:

Couple of Turbo Tracks, quite a few Wreckgars, a smattering of random scouts, one or two Lugnuts, Strafes etc.

Oh and if you haven't already seen, deluxes are $18 and voyagers are $30. Can't believe I didn't pick anything up.... Then again I have no money so you can see the logic there.
