i was just at target and they have a yellow deluxe car wash mitt (around $6 IIRC) that was pretty soft and seemed to be a synthetic sheepskin type of mitt. might be worth checking out for some...
Try Ebay dude. I got 25 MF towels with customized color choices for a little over $1 a towel SHIPPED to my house. Also, the blend was 80/20, which is better (from what I have read) than 85/15 sold OTC.
I know I can get VERY high quality Mf's for $$$ online at places, but I'm not willing to pay $40 for 6 Mf's(that's how I feel, so let's not get into that discussion please).
