I really like Peggy's meshes but the hair colours are too shiny for my taste! Mostly I download from the sites you mentioned above but not so long ago I found a site with great hair recolours! http://txprincessshansims.blogspot.se/ I love it.
I'm really liking Trapping especially her TS3 to TS2 conversions, and Skoogy , and AlmightyHat. Trapping also has a lot of good hairs on GOS. Also all the usual suspects like Nouk, Peggy, Raonjena, XMSims.
Has anyone looked into Skysim hairs at TSR? They are all free (and very beautiful) and I have been having download binges. The only issue is for red-heads -the color is a lot pinker/brighter red than I feel would be appropriate for realistic gingers.
