I'd just had a run at this my self, deciding for Aramith or Brunswick:

There is a big difference even in between the Aramith SuperPro and the SuperPro TV set!
Both sets are used in two different pool halls and the TV set feels heavier and harder to get english with than the SuperPro which feels like "toys" compared. I'm pretty sure the TV set is also bigger in diameter but that I have to measure to be 100% sure.
So going for some cheap balls - if you have a good table - could put you in a strange spot when you enter a tourney where they use a TV set or similar.
I did go for the Centennial, but then that's just me.
