Unless the price has changed lately, Advanced was $1995. After tax (if applicable) it will get over 2k but then the $750 amount would also increase for Basic. Both include a year of unlimited support and updates. 

There are many differences, but what I'd say from your explanation of what you're using it for....get Basic for now. It will do everything you said, and if you feel like you need the Advanced features you can upgrade for the price difference if you're still current with support. So you're not out anything if you want Advanced later. 

If you have specific questions on the differences, ask or call them.
