Perixx MX-800, up to 2500 dpi. I got mine for € 8.

Then you might want to consider this layout.
Blue keys would be for punctuation
Yellow for regional (in our case accented vowels)
and Orange for math.
Brackets would need to be assigned somewhere else.

Hi, I'm new here.

I've been thinking about this as well for a while and I came up with pretty much the same layout gianni proposed.
Although there are a few issues to address.
1) Angle brackets are lost to the left shift key, so they could moved to the Z and X keys with the CTRL+ALT modifiers ...
