What are the BEST FREEROLLS out there?

[Tharpab]

Is there any site offering great freerolls, most of them
demands certain amount of hands played, etc. UB tournies are nice but is there any others with nice cash prizes?

Crypto skins have $300-$500 during the week (not worth it?) and a $3000 on saturdays. I don't even think you have to deposit to participate, just d/l the software.
