Do you use any alpha hydroxy acid products and which work best?

I have used the brand Alpha Hydrox, but am having a hard time finding it in the stores now. I used to love it.

 My first AHA product ever was Peter Thomas Roth Glycolic 10% Moisturizer just this winter.  I wish I had started using AHA much much earlier as lately this is the only thing that works to help control my acne!  Since then I've found other, low-cost alternatives that work well and are better for oily skin (the PTR is lovely but of a creamy consistency better for dry skin).

c. booth (found at Rite Aid) has a nice 10% AHA liquid

Alpha Hydrox is great too, I'm using their 14% AHA pads once a week, and the 12%AHA souffle as a spot treatment.  (found at Ulta or drugstore.com)

Planning on trying Glycolix 20% pads sometime, these can be found on various skincare online retail sites like dermstore.com
