I haven't had experience with high colesterol but might I suggest you read a copy of the new dietary revolution by Dr. Atkins. People that are overweight usually start the atkins diet but as he states in his book, you don't need to be overweight to follow the diet, you just need to want to feel healthier and happier.
To get to my point, i've known several people so far to follow the diet and they've watched their high colesterol and high blood pressure lower to a normal level.
Of course this is only a suggestion, it's up to you to read and then follow the diet but I believe that it would work for you and it is better than paying for pills that may cause adverse side effects.
I've been reading the book myself and I am going on the diet beginning this weekend and eagerly looking forward to it now that i've been educated. Hope this information helps you.
