Your best bet is a auto recycler. Check carpart.com first to get a general idea. You might find one for less than $100 if you look hard enough and can drive to pick it up.
i want to spend as little as possible i found one from an ek for 50 but just found out it was sold im going to check the local junkyards and keep checkin craigslist
I have a VX trans I would be willing to part with. Got it as part of a swap I bought, but I had another transmission built already. If you're still in the market, I've got one. Haven't driven on it, but the guy who sold it to me was the only owner and got rear-ended at 150k miles which totaled the car.
I'm near Ann Arbor, MI, so it's a bit of a trek, but if you're willing to drive, I'm willing to sell.
