I actually have an old nostromo but am looking for something better. I found one item, it looked kind of interesting, but I'm not completely sold on it:

I've found other stuff, but they're super expensive. This is one of the cheaper models I've found:

But I've since started searching for a gaming mouse. I found this one. Any idea if it's a good model:
