How much to sit down with here?

[henrikrh]

1/2(pounds) at the gutshot PL HE. The min buy-in is 50, which is waaay too little, absolutely stupid. I sat down with 60 like an idiot, just to test the waters for later tonight, and lost most of it on AK vs QQ preflop. Anyways, I don't feel secure sitting down with 200, which is what I would guess the right amount to be. Some people sit around with 500-900, which is a bit intimidating, but their play wasn't anything great, lots of stradles, no hands didn't see a flop. Would 100 be enough, or am I wasting it? If I get a single decent hand I know I can get it paid off, but if I don't I could get blinded too quick to save myself. And I value the experience of sitting down and playing what to me is pretty big stakes, the experience is good and very educational.

Edit: More info. 200 is too much for me to lose, it would have me beating myself up for weeks. The lower limit gmaes are raked out the wazoo, but are decently juicy.
