Good day.

Before I bought my cnc the top 4 machines I looked at was Avid cnc, Cammaster, Shopsabre and Legacy.

I choose Avid because it was modular (you have to assemble the whole machine except the electronics cabinets).
I knew that I need to move the machine in the future and a forklift will not fit.
I have a 5x10 table with router, plasma, rotary lathe and this week I added a laser as well. I looked into the ATC as well but it is not needed yet and
I rather spend the money elsewhere for now.

I needed to know everything about the machine because if something need to be repaired I need to do it myself and the parts could be bought from a different sources as well.

My advice if you are committed to buying a machine, buy the one you want and need the first time. Also make sure whichever machine you buy has great support ...because you will get stuck at some point.
for me I knew I needed a big table and wanted to add the plasma addition.
but when I bought it I did not buy the plasma electronics and water table. after I had the machine up and running..I bought the plasma addition.
If I bought it the first time It would saved me money on shipping and time installed.

On the software side ...
I use Moi3d probably 90% of the time and the rest would be Vcarve pro. Tried Rhino but I do not need it for now.
Right now Learning Blender and 3dcoat for more artistic stuff (this will take a while). Alibre is on my list to learn parametric and the motion simulation.
Last week I was looking at Meshcam and Deskproto but since Vcarve is doing what I need no need to buy additonal software for now. Vectric software is very nice.

I do not think the model you posted should be a problem for Vectric Aspire or Vcarve Pro but not made in 1 go. (Modeled first in Moi since it's faster imo) even the top and bottom part you should be able to make without a lathe just the cnc with the correct bits.

Here is a video of Avid rotary in action (not mine) https://www.youtube.com/watch?v=wr7ckMyfCmc

I wish I have bought my cnc years ago.

Merry Christmas to all.
