Stars has .02/.05 and .05/.10 tables with a max buy-in of $10.
There's little difference between the two imo except for the fact that play is a tiny bit better and everyone isn't shoving as often and as loose. Don't get me wrong, they're definitely loose everywhere in the micros, but you'll see what I mean after playing a bit.
I assume the blinds are different for the two levels at titan.
In the case of stars, you'll find that buying in min at either is probably not the best idea. Put a buck or two on top of the min imo, or you'll be crushed by people who buy-in for max. If you have a small BR, don't risk it at those limits and consider going down to the .01/.02 tables (if they have them).
The bigger blinds also affects players. You'll be able to tell that if you sit down with one or two short-stacks whether or not they're folding or calling stations and you can take advantage of it.
