I'm playin in a .5/1 NL live cash game tonight, and haven't done it (NL) in a while. Weird thing is, the host tells me most guys buy in for $20? and some for $50? The max he tells me is $70.

Any changes in strategy here? Will buying in for $70 give me a weird table image? I've never played in this game, and 1/20th of your stack being the BB seems like it might be a push fest.
