OK, so going to Cash Casino basically means a 19% rake at a $50 buy-in. On a buy-in of $105, the rake is 7.6% if Hairgel's info is correct. If we are only getting 10 people, we can obviously play at home.
This leaves us some choices:
1) Play at people's houses - whoever hosts a given event will announce how many they can accomodate (e.g. I can probably seat 14) and people sign up on a first come, first served basis, which in practice means a hardcore group of 6-8 that will show every time + a few extras who want to play any given week.
2) Play at Cash Casino and deal with the rake. If this is the option, I would personally want a higher buy-in, so that money goes to us instead of the house, but this is up for grabs. This choice is only good I think if 20+ people can commit to playing regularly.
3) Keep looking at other options - for example, does anyone have a large heated garage that can accomodate 2 or 3 tables? Does somebody have office space that can be used for this? Does somebody have other ideas?
