I have the 3" (<a data-hook="product-link-linked" class="a-link-normal" href="/OXO-Good-Grips-3-Inch-Mini-Strainer/dp/B001713L84/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">OXO Good Grips 3-Inch Mini Strainer</a>), 6" and 8" strainers in this design.  The 3" is extremely small so personally I would recommend buying only the 6 & 8" sizes unless you have something in particular you would use the 3" strainer for.  Overall these strainers are very sturdy, the handle is solidly fixed to the strainer, and the mesh is very rigid and keeps it's shape well (you can't poke it and make it deform).  The holes are very small which allows you to strain almost anything without losing part of what you're straining.  These may be a bit more expensive than your average strainer but the quality makes them worth the extra money and I'm confident they will hold up for a long long time.
