The only Lightroom presets I use besides my own are the ones from Pretty Presets. :-) So I wanted to let you know that the Pretty Presets "Summer Limited Editing Set" is on special right now for only $39. I have this set and love it!
And if you haven't checked out the Pretty Preset Blog, please go visit when you get a chance. I have learned so many Lightroom editing tips and tricks from there.
