If the scratches are due to something being dragged acros the counter, they can be sanded out with a little elbow grease. Using wet/dry sandpaper, start with 220 grit. Make up a solution of water with a little Dawn detergent in it. Put some of the water on the area to be sanded and work the paper for a bit in small circles on the scratches. Rinse with clean water, wipe, and reapply the soapy water. Sand again with a 320 grit. Repeat the process using 600 grit, then 800 grit, and finally 1000 grit. Follow the 1000 grit with an automotive polishing cream (not rubbing compound), following the instructions for it. If you want it really slick, apply some MacGuair's paste wax.
Some procedures recommend using different ScotchBrite pads, if you can find them. The fine grit papers are easily found at any auto parts store.
I had to repair some serious scratches in my counters after thieves dragged their asses over them to steal the TVs from the rig. Took less than an hour and they looked good as new. But for the minor scuffs and scratches from normal use, I'm not too concerned with those.
