My wife loves her coffee (not me, hot choc all the way) and we had the REI lexan french press and it was pretty good.
Now I have a stainless steel press and it is nice since I have heat the water directlly in it and reheat or keep the coffee warm in it without worries about the lexan.
I'm in the coffee business. I'm a real snob when it comes to coffee. But I also like to travel as light and simple as possible.
I like a French press at home, where it's easy to clean up. But out in the backcountry and on the road I use a pour through "coffee maker." It's a plastic cone shaped filter holder that sits ontop of your cup, thermos or pot.
I like these because they're small, light and easy to clean up.
