The commands and process is the same from VCP to Aspire for everything included in VCP. Vectric has very good tutorials and a great user forum.
You can watch some of the tutorials on YouTube, and they have an annual user group meeting in the fall (tuition required).
I would try to be more specific about what you are looking to do 3D before spending too much energy on a decision. There are now programs which will convert photos to STL models. That may be enough to get you by for your needs. You can also hire others to do modeling for you.
My son purchased one of the first SO3’s 3 years ago when they were introduced and his business product line has evolved significantly over those 3 years for a number of factors. Things that he thought would sell and use the CNC for didn’t have a market and the capabilities of the machine opened up other opportunities for him. He has been able to do everything required with V-Carve Desktop and V-Carve Pro. He now has 3 SO3’s at the age of 18.
In short, what you think you may need for your future needs today, you may not need it nor may it be supported in five years.
