PanOxyl for acne? (product, cleanser, peroxide, acid)

[Opsimathia]

I was looking for a acne product that had Benzoyl Peroxide in it like the proactive. Proactive is about 2% in the regular line. The PanOxyl comes in strengths 4-8. It is MUCH cheaper than proactive. I just wondered if anyone has used it? I was thinking of giving it a go since it is the cheapest I have found with BP in it.

My skin is pretty clear now so I was thinking of switching to keep the occasional ones at bay and maybe using something less harsh than acne cleansers on a daily basis. I wonder if this stuff is strong enough that I will only have to use it during a breakout.

p.s. looks like I should seek something out that peels away the dead skin. Proactive has a glycolic acid in it too for removing the dry skin the BP can create. Manual (brush, cloth etc) or acid? Hmm....
