recommendation for Yeast?

[wish_Fish]

I have been using Yeast-sugar method to generate CO2...they work well for me but i have to change the mixtures almost every 4 days for strong productions.  I have tried a couple of brands but neither of them barely last very long.
anyone has any recommendation for a particular brand that works really well (last longer)?

Yea pressurised  , no more mixing or changing for a long time   
Have you tried brewers yeast ?

I think Dan always reccomends brewers yeast from some Brew Your Own place on Bank Street beside McDonalds near South Keys.

More specifically, you can ask if they have any yeast for making champagne.  It is working great for me but to be honest I have not tried any other types of brewing yeast.
Also here's a power point presentation some guy made that has a lot of good yeast info.  I realize that you're already pretty experienced but you never know when good information will help.
