Is a stainless steel french press good to make coffee?
Thierry,

Stainless steel French presses work fine.  In fact, you can construct a French press out of any chemically inert material: stainless steel, class, ceramic, high-temperature plastic, enameled copper, even marble, and it will make perfectly good coffee.  I myself have a collection of porcelain and stoneware presses.  What material you choose is really a matter of aesthetics and how you use the press.

All of that being said, my experience is that high-quality glass carafes do not break regularly unless you drop them (which is, admittedly, an issue).  I'm wondering if you bought a cheaper carafe with inferior glass, like one from Ikea.  I have a Bodum which is at least 8 years old.

Also, for brand name presses, you can usually buy replacement carafes, since breakage (due to dropping) is a frequent issue.  Sometimes the replacements cost as much as a whole new press, but you should at least check it out.
