I love finding good freebies even though I also make things for sale. My favorite finds are:
* 4 pairs of Tesla heels from a lucky chair
* Relance entire store
* ETD hair
* Another Skin
* Immerschoen
* Inga Wind <-- new designer with some really cute stuff!!
Of course I still have all my Barbie dresses in a box since they bring back memories of my first month in SL.
I give away outfits in my Ends & Odds group now and then (which doesn't match my store name lol). Occasionally I'll throw something I normally sell on XStreetSL up for $1L for a few days. People just have to watch for that.
But really, my favorite things are always by other designers since I spend so much time working on my own that I get tired of them when I finish.

And if I find something really cute that's free, I'll almost always try to buy something from that designer. One thing, never put something crappy out as freebie! People will assume that's a sample of your work quality. If you made something for practice that didn't work out, trash it or put it out under an assumed avatar!
Oh and another thought. If you think something free is bad but the designer looks well intentioned, let them know how they can improve. I love feedback. I think people are afraid to give it though so things that are wrong with your outfit may never get fixed. Although a few designers I've offered advice to have not taken it that way.
