I might consider playing one of the pokerstars deepstacks if it was one of the bigger buy-in affairs. I played a $20 or $30 one once (can"t remember what buy-in they are now, but it wasn"t a lot), and after about 2 weeks of grinding, I was in the money - but still 4 hours away from the final table (where the proper money is).
No way was I going to grind it out with a mediocre stack, so instead I decided it was glory or bust. If I was going to be playing for another few hours, I would have a decent stack. Of course, it didn"t work and I busted out, but at least I got some sleep that night.
