Your only real option for on the weekend for a decent tournament close to your specified price range is going to be at the Orleans at 7pm on Friday and Saturday. Buy in is $105 total ($60 buy in, one $40 rebuy, $5 dealer add on). Sunday tourney is at noon, $80 ($75 buy in, $5 add on, no re-buy) total.
I know, I know it's not on the strip.
But be forewarned that playing the tourneys at Sahara or Flamingo is just gambling in a crap shoot, as the structure makes for an all in shove fest. You are better off gambling on craps or blackjack
, as you wont have to fade as high a vig as the entry fee will be in relation to the prize pool.
If you are willing to spend more money for WAY more play check out Binion's at 8pm for $200 (Fri, Sat, Sun), or the Hilton at 1pm for $170 on Saturday (about the same as the Orleans as far as structure).
Please, please, please, do not waste your poker money on -EV crapshoots.
Say "NO!" to bad structure!
