First question, are you hoping to make money with it, or is it for hobby use?
I own a Tormach PCNC1100S3 (last version before the mx). I run Haas machines (including a vf2) daily at work. IMO the Tormach is fine for the hobby grade stuff I use it for at home. If I was anchoring my business with it however, I would go for the VF2 without question. Especially for the cost that new Tormach's go for these days. At it's core the Tormach is a hobby machine with add ons that dress sit up like an industrial machine. IMO they've priced themselves out of the market they created/carved out for themselves, and are now at a price point competing with other machines that would run circles around them. I don't have a toolchanger on mine, but from what I hear the toolchangers are not the most reliable anyway. One reason I wouldn't rely on it for business. You need to buy time, not have to babysit the machine all day. The haas (or any other industrial machine) wins that hands down. But not without downsides. They each have their strengths and weaknesses. I can elaborate on more specifics if you like.
The only reason I'd choose a Tormach over the Haas is for space, and power concerns. Price is one too, but if you have the work/products to support it, it is less of an issue IMO. The first 2 reasons are why one is in my garage. Machine wise, the Haas wins hands down. I don't regret my purchase, but I use it differently, and for different things than the machines at work. I also didn't pay new prices for it either....
If you want to make a trip out to the east GTA (near the 407/115 interchange) you're more than welcome to come check out my Tormach.
