Marty- You may have made a math error (like it did a few days ago. You've used up the whole budget on TT, 2 arms, 2 armboards and 1 cart. I know its pretty close, and you could probably do something with a SOTA for example, 2 different REGA mount arms (need only one armboard) and 2 carts. But the hassle of installing a new arm on the old armboard would be probably more than installing a diff cart on the arm. Maybe that's the way to go, now that I think about it. Get good at swapping carts and go that way for a while, until you can afford a second arm. As for me, I would be VERY careful on a used cart. I've sold one that was in great shape, but there are lots of posts/disputes in the forums about problems with used carts. If you can get one from a very reputable member and get a detailed provenance, then its fine, but otherwise, a real crapshoot,IMO.
