I would strongly suggest that you take an actual test drive on each of the lathes you're considering. I know the VB headstock has a small footprint, but once you add the tailstock you've got a real space issue on your hands. Yes, I know about the small-version tailstock, but if you're looking for significant added stability, I rather doubt its ability to substitute for the full size tailstock when cutting larger sized piece of wood. You'll also have to figure out where and how to store all that iron (Tailstock, beam, and structure) when you're not using it. The VB is a fine machine, but I passed it by because I simply did not have the space in my basement shop, and the add-on tailstocks quickly took the price over $8,000 plus freight.
I turn on a "short-bed" Stubby 1000. I don't know which Stubby you saw, but I can tell you that I am continually working on a piece from the full 180* from the left side clear around to the right. All hollowing is done straight in from the end of my lathe. Functional bowl clearance is 40" in diameter by about 10" deep when using a chuck; an inch or two more depth can be had using a faceplate mount. The articulating beds allow solid access to the workpiece even out at the 40+" diameter point, yet I can still turn a 36" long by 19 1/2" diameter spindle-oriented piece with the basic configuration. My lathe uses a 3 hp TEFC ac motor and Eurotherm drive which provides excellant torque on the low end of the VS range. A good motor, but not one designed for lots of slow speed (less than 100 rpm) work so it will tend to get warm because the cooling fan is also running that slow. I therefore use a small muffin fan on the wall to keep the motor cool when I use the lathe at very slow rpm for sanding and finish application. I was able to stall the spindle while turning a 28" bowl using a Glaser 3/4" gouge, but then I had the tension on the poly-v drive belt a bit loose for safety.
Since the 1000s are basically now made to order, and you're left-handed, you can inquire about having Omega cut the spindle threads for the left so you can run the lathe clockwise without unscrewing your chucks. You will, however, have to get adapters and faceplates cut with lefthand threads.
