You are thinking of fee-only, which sounds very similar, but is vastly different from fee-based. Fee only is what you want. As it happens, Scott Adams appears to have meant the exact opposite of how he’s been quoted! Scott specifically meant to warn people off financial advisers who charge a percentage of assets. Fee-based as a label appears to exist purely to confuse unsophisticated consumers, by sounding so similar to the (good) fee-only label.
