This ontop of this
The mouse (Which is the Logitech G5 Gaming Mouse) has superb precision for me, and since the mousepad is a perfectly smooth/flat surface (It's also overly-sized), this awesome mouse glides around with absolutely no resistance. The mouse also comes with a weight system so that if it feels too light you can add more weight for a more heavy feel to the mouse.
The mouse itself costs around $30-40 whilst the mousepad costs about $20
