I haven't owned one but have been considering them recently myself; there are several nice looking candidates at the moment on the Bay. Yes, I've regretted parting with our Toyo; but moreso for your sake as you've been deprived of your 4x5 and other kit (I at least have the Linhof).
I know Wista are highly regarded among US LF forum members. They have a reputation for ruggedness and good construction, and I have a hunch that they are pretty competitive with Toyo in those areas. Their design concept seems identical, with similar movements at both front and back. Personally I would have one without reservation. There are several models: the older (and cheaper ones) are the D, and the later ones are the SP and VX. There is also a wooden one, the DX, which can still be found as new old stock, as I think Wista are now out of production. If you like wooden cameras (I do), the DX seems to be identical with the Tachihara 4x5, of which I've had two in the past and also regretted selling. When will I learn.
Good luck with your search, and keep us in touch.
