Ok, it's not looking good now.. Their software is a print only deal, zero design options in it. Design software goes from basic free to $3000. The Ez3D software is available for DL, but didn't do anything except look for a connected 3D printer when I tried it.
If you want to play with designing in 3D with no download, https://www.tinkercad.com/ It has some functions and tools (group,scale,etc) that will be familiar to many people
Below is a response I received today, and awaiting one more follow up.
Hi,
So our software is not actual design software. It takes a 3D file and just translates to the printer. So the software you would need is a 3D design software, specifically one that exports in .STL format (which most do). The price range will be huge, you can spend a relatively small amount on a design software or spend thousands. But for our printer all you need is one that can export into .STL and our software does the rest. Does that make sense? I would look at our software like iTunes. It can print your .STL files and also store them in a library so you can easily organize your prints, it just cannot make the .STL file. Hopefully this makes sense! You should check our the videos we have posted about our software: https://www.phoenix3dprinter.com/support.html
This makes for interesting reading, and doesn't instill confidence.

The pricing has went from $399 to $699 in little over a year.
I will be waiting to decide until a later date.
