I just went through this.
I'm in the process of getting our Weeke Omptimat 480 setup.
I had an extremely negative experience with CabinetVision. To the point that I will use every opportunity to convey my discontent and encourage others to avoid them as well. If you wish to talk to me about it send me a PM or call me.
I bought a 3 month trial of Mozaik a couple of years ago to try out. I was not impressed. It felt clunky, and just not intuitive to use. I did not make use of the free training that came with it, so I did not give it a fair shake. I also really hated that it did all of the rendering in Sketchup. It no longer has to do that, which I like.
I knew that next year I was planning on getting a router for the shop, so a few months ago I downloaded it again to try it out. Once again, I did not make use of the training, but I did play with it a bunch more. A couple months into the three month rental I bought a used cnc. I also bought a key for CV at the same auction. After my experience with Vero and purchasing that key, I decided to go with Mozaik. Now that I've got some training under my belt, (about 4 hours worth), I'm getting more comfortable with it and getting things dialed in with my parameters and I'm getting more proficient at writing formulas for the odd ball way that I like to build things. It's far from second nature, but I'm getting there.
Mozaik wrote a post for my router, though it has been untested yet. I kinda fell through the cracks with regards to getting a tech from Stiles to come out and do initial startup on my machine. I take a fair amount of blame on that as well because I didn't follow up. I hate being the guy that bugs others, but at the same time, patience isn't always a virtue. Either way it's not a big deal.
I have complete confidence that Mozaik will make it right if it isn't in regards to the post. They've been super responsive, very helpful, they have a ton of resources to help yourself, and the training has been fruitful. Plus, I think they have an excellent business model. I don't feel raped. The CNC Complete Version from Mozaik costs less than my maintenance fee would be with Vero.
CV is pretty powerful, I know from talking to others that it has it's limitations just like anything. The interface is pretty nice too. But their way of doing business does not jive with me. It works well for a great number of people. It is a bonkers expensive setup though.
One of the things that really encouraged me to go with Mozaik is that you don't read anything negative. I believe these boards give a pretty fair assessment of things. Mozaik always gets a positive review. I don't feel that's as true with CabinetVision.
Good luck. It's a tough decision and one you will have to live with for a long time.
