The aforementioned combo certainly falls within the OP's financial wheelhouse, but I like jim e's advice with respect to an upright stringer as opposed to a tabletop. If going with an upright stringer puts the wise on hold for a few months that's fine in my opinion. Learn to string on a lockout then move to a wise; you'll undoubtedly appreciate the wise even more. Plus, if you ever have to return the wise for repair, falling back on the crank--although painful (been there)--is a better option than being sidelined altogether.
Just to be clear, there's absolutely nothing wrong with a tabletop, but for what you want to ultimately do with your machine I think an upright is the better choice
