Best chinois, mesh strainers?

My niece told me she just broke her old mesh strainer (making tomato paste). This is a great opportunity for me to add more things to her collection that I've been working on over the years. I've already selected an immersion blender for her (the Dynamic MiniPro MFR # MX070.1), which is supposedly one of the best options available for immersion blenders. But I'd like to ask you professional chefs/enthusiasts again about :

#1. fine mesh strainers and
#2. chinois

I read a few links, such as :

But I was wondering if there are any clear trusted high quality commercial products pro chefs use that I should depend on? Hopefully it is something made in the USA or Europe. Also, if possible, can you include what sizes you feel I should get her so she is able to make anything in her cooking attempts? Cost is not really an issue as long as it is high quality, efficient, etc. (I don't care about aesthetics). If I need to get three or four different mesh strainers and two chinois, then I'm fine with that as long as she has whatever she needs.
