I use the same "bowling towel" espressme found on Amazon.
The Amazon seller also offers them on eBay for $5 (w/o the shipping charge).
http://shop.ebay.com/merchant/ducky_boy_golf (If you look down the items for sale you will find a dozen or so auctions for the Black Microfiber Bowling Towel Strike Force Top Towel)
They are a good size - large enough to get the job done (14 inches by 16inches) but not too large to be unmanageable from a maintenance perspective.
The black microfiber itself - after a wash and tumble dry - literally "shines-up" everything from the machine to the counter top, is very resilient and is quite absorbent, in my opinion...
Because they are graphite-black you can still see when the brown coffee grounds start to accumulate, you can give it a shake over the sink, a good rinse and hang it to dry on the faucet.
The microfiber seems to dry cleaner (and faster) than cotton and every few days you can pull out a new one and throw the older one into the laundry.
