Bob and Sharon, Thanks for your help. It is very difficult to evaluate the contradictory information when my personal knowledge is so limited . Sharon, I'm sorry your sister's experience was so disappointing. I think I will pass for the time being, my problem is not severe enough to risk it. Thanks again.
