I own an old Variax Acoustic 700, and use it for coffee house and winery gigs during solo acoustic sets for special tunings. Line 6 abandoned the Workbench software, so I have to keep an old Mac laptop specifically for use with the guitar. So, my comments echo @Brue58ski's. I'll have my old strats for many more years and the value keeps going up, but the Variax will get harder and harder to get support and hardware for. Its like owning a Model-T after awhile; you have to learn how to maintain it and where to buy parts.
Even so, I bought a newer used Standard at a good price a couple of years ago, and keep it around mainly for special tunings in the studio. Its good for that, I think (I wouldn't own it for banjos, sitars, dobros acoustic guitars, etc). There are artifacts with some tunings, but they are usually buried in a mix.
