So where's the best places/nights for Karaoke in LV?

[Daliman]

I'm already familiar with the IP's karaoke every night, but the talent, both singing and female, is spotty at best, and the waits are long, even with tipping heavy. Ellis Island I'd heard good things about, but I've been there before, And I have a policy that when I go to any bar where I actually LOWER the average age, I tend to not have a good time. BAsically, I'm looking for a place to show off, drink tons, have some nice looking women around for the other guys in tow to pick up and me to live vicariously through, and have a good time all around. Yes, I know Karaoke isn't always going to provide that, but are there any better spots?
