Hi, so I play many local games, and it's a constant struggle finding the right combination of action and "reasonable rake"

The lowest rake around town is 10 dollars cap. 10%.  The highest raked game I play is 15 in hold em, and 20 in omaha.  In your opinion, how much money would need to be on the table to justify the rake?  Also, assume the games are very good, not nitfest.  The games are normally 2 rounds hold em, and one round omaha.

Any comments and feedback and personal experience with home games are welcome.

Thanks!
