I'm shopping for a 40x20 vertical right now, and happened to get comparison quotes for 30x20s from each brand we're considering (Kitamura vs Okuma). The 30x20 machines seem to be consistently about $10k less than a 40x20 machine, so I haven't found a reason to justify the loss of 10" of X travel for a relatively small increase in price. Pretty much everything out there with basic options and a probe will run in the $110k range for a 30x20 and the $120k range for a 40x20 from what I've seen. A rotary adds about $15-20k for the rotary table and drive, based on the quotes we got for a nice Koma setup. These have 30hp, 15k RPM spindles and move fast enough to scare you. I'm not sure if there's anything that you can buy new that's much slower out there these days, at least not anything that would be significantly cheaper.
For reference, a VF2SSYT with a probe, most of the options, a 4th axis drive, 210mm rotary, and 1k psi TSC will run you about $122K delivered. We cancelled that order the moment we realized we could have a 40x20 piece of Japanese iron for virtually the same price, just without the rotary. It'll run circles around the Haas, and comes with the options you pay out the ass for with Haas by default. That VF2 is about 8000 lbs compared to an 18,000lb Genos M560V. They say you shouldn't sell machines on weight alone but...yeah. There's something to be said for sheer mass.
The only reason we were initially going to go with Haas is because we're on the 6th floor of a mill building and our freight elevator can only handle 8k lbs. The next machine is going in with a crane, 120' in the air, because rigging wound up being a LOT less than we thought. Still would've had to pay to have the VF2 partially disassembled to fit it in the door, and that made the two options roughly equal in price after paying a HFO tech $3500 to take the toolchanger off.
Don't forget to budget for tooling if you don't already have CAT40 stuff, which it sounds like you don't. Both mills I'm looking at have dual contact spindles, which can use regular holders as well (cheaper) while sacrificing some rigidity. Our dealers typically do a 10% tooling allowance on financed machines, which is usually enough to get started with the basics.
