We only use Cisco at my work. They are more expensive but they hold up well and support is good. Next day replacement delivery with smartnet.
Take a look at the HP line of switches. I haven't used them but have seen good reports on them. I would think they would meet your needs.
I would also recommend looking into the HP series of switches, they are very reasonably priced for what you get, and many offer lifetime warranty and support here in the US. We have used several of their cheaper small business switches for some small businesses, so I personally don't have much experience working with the high-end networking equipment on their lines, but I know that the university I used to work at while at school used all HP networking products and were very pleased with them.
