I never really understand the argument against Microsoft software being out of the range of reasonable expenses.
Certainly for all the corporates I have worked at, Ultimate is well within their budget.
But Ultimate really comes with all the bells and whistles. If money really is an issue, and you find you must "Collect and analyse runtime diagnostic data from production systems" or "Reliably capture and reproduce bugs found during manual and exploratory testing to eliminate "no repro" bugs" then there are better tools out there.
I've worked for a long time with Premium[2] and never felt like I was missing features...
