if looking at cnc routers you have 2 different type.

you have flat table router style that has a sacrificial MDF table that vacuums that suck the part to the table through the MDF. These work very well for large items. The only time I have had issues with them is when I start with a 4x8 of white melamine and start cutting drawer parts out of it. The more cuts you make through the stock the less vacuum there is to hold it in place. These can be had relatively cheap and have a bunch of tool holders. the last one I used had 8 positions. The biggest cutter we used was a 6" flycutter for smoothing the MDF when it got to rough from cutting cabinet parts.

The other style is point to point. this uses a series of vacuum pods that hold your piece in place. These work very well you just have to be much more careful if you are penetrating the board so you don't hit the rails or pods.

The flat table is quite a bit more versatile especially with what we would all be thinking of using it for. you can get lots of different configurations. 1 table 2 tables this gives you the ability to load one table while the other is running. The sizes have gotten pretty large to.

Another great feature of the flat table is sign making. throw a slab on the table, surface it, then cut whatever the customer wants. That is where the 8 head toolholder comes in very handy.

I was exposed to all these fancy tools when I used to work for a bunch of cabinet shops. The general construction was adjustable shelf holes with dowels and then clamped together. Just basic casework. but the flat table router really excelled being able to throw a 4x8 on the table cut all the parts to size and then drill all the adjustable shelf holes in one step. The guy we had running the cnc also did our plastic laminate layups. he could layup 2-3 sheets in the time it took to cut 1 sheet of cabinet parts. Worked out very well for use. the guys building never had to wait for parts.

About 2 years ago I sketched up a router sled I will be making to fit on my mill someday when I get the time and extra money. It will be a cnc setup controled by GRBL using steepers that will be a belt drive and use an Infinity planer bit in a big PC router. Just drop it on the mill, tension the x drive belt to the mill tracks, set 0,0 on the slab corner, choose the proper  lenght x width code and watch it run. Self contained and runs on 120 volts and will be between 300 to 400 pounds. It will also be useable to make large signs just like a 12 foot x 24 inch cnc router :)

I am really interested in following the progress on that. I have thought about something very similar. Now that I have a 50" mill bed that would make life quite a bit easier.

I can't say much on CNC in that price point.  Much more $ than I could budget and haven't investigated.  (My current CNC router is a homebuilt 2'x4' model for about $1k.  I use clamps and T slots instead of vacuum hold down.  My dream setup is either 4x8' or 5x10' from CNC Router Parts would be about $6-8k all told.)

For commercial models though, I hear good things about Thermwood and Laguna.  Thermwood also has a program where people can use their FREE design software and send the file to participating Thermwood owners to cut on contract.  Like hitting the print button, but for cabinets.   ;)

Shopbot Tools is middle of the road for price, has a great reputation, and is US built.  If the weight capacity of their table matches what you have planned, it could be a great option.
