The Cal Neva has a pretty good promotion for new members going on. Play for an hour (not sure how fast you have to play) and they will match any winnings or losings up to $200....You get the bonus $ in free play, which I assume has to be played off until it can be cashed out, but this still seems like one of the better new member signups currently around.
Also, a while ago there was a Shockwave query. The Nugget in Carson City has 12/8 Shockwave, 25c, on some of their bartops....
