ArcDroid seems very straightforward to me, but still we should all eventually learn CAD for the future, which the ArcDroid accepts.
The downside is the cut size but that really depends on your end goal, it may or may not suffice.
You can always build/buy or adapt something for a water table and a cutting area. I found a very simple design that quite honestly you can build yourself using the 30 Air and adapt an undermount metal kitchen sink (use it like a drawer) to hold the water, drain it and catch the cuts. Maybe @Andrew or another user can someday, design the bracket/brace and provide the same in the proper format for anyone to cut and build whatever size cutting platform they want, it could help with sales!
