I happen to like the ones from TOL and Florida Sponge Company (the latter courtesy of Spilchy...thanks Spilchy!). You can also get good ones from ABC Window Cleaning Supply, but you need a minimum order of $45 (not a problem for me as I like a lot of their brushes and bottles and other odds and ends--and who doesn't need a plastic 3-D Coyote to keep birds away from their car

).
ABC Window Cleaning Supply, Inc. - Detail
Top of the Line Giant Sea Sponge
I didn't really care for the ones from Autogeek though--just my preference. So if you don't like your mother-in-law much, I'd get those.
You're welcome! :2thumbs:
I also have great luck with these guys:
Buy the Acme Sponge & Chamois Company SW#1-1011C Sea Sponge, 10-11 inch at Hardware World - The world's #1 home hardware site
The ones I got from them were awesome. They had huge flat surfaces the size of a sheepskin.
I love the sea sponge because when wet with soap, they are softer than silk. Nothing is as "orgasmic" feeling

It's amazing. Also, nothing else comes closer to rinsing cleaner. The grout sponge can't compete with these features. Further, they swell to a "million" times their weight in water. Nothing holds more soapy water. In fact, I have to dump out my rinse bucket because it over flows and some times I have to make a new bucket of wash solution! That's how much water they "sponge" up and then release. They fit into every nook and cranny imaginable. You can take an 11 inch or 12 inch sea sponge and squeeze it into the size of a golf ball in your palm. Sea sponges last a long time so the steep price pays for itself in the long run.
Nothing is better than the real thing. Just like sheepskin comes straight off the animal (the hide is in the inside of the mitt) the sea sponge comes right from the ocean. They are clean and safe to use just like anything else that comes from the ground or an animal. They go through a cleaning process. A quick rinse and you're good to go. I have NEVER experienced any damage because of a new unclean sponge. The fear is so overblown that it is ridiculous and I've become tired of calming people down. Most people who bring up this "fear" are those who haven't even used it. But for the most part, those who use them regularly will agree with me.
If sea sponges were cheaper and the overblown "fear factor" were not issues, I guarantee it would be as popular as sheepskin. If people will rub a cheap, synthetic, fake sponge made for tiling floors and walls then I suggest trying the
real thing.
The one thing sea sponges may not be good for is ONR. I have not used it with ONR and there was a bad experience here about it.
EDIT:
Anyone wishing to try one, it must be a Sea
Wool Sponge. Acme makes a very good sponge as well as Florida Sponge Company. Try to get unbleached.
