I'm not against them, per se, its just that you seem to be fearful of owning an old car with sh1t brakes and you've stated a desire to move heaven and earth (at great unnecessary expense) to avoid a braking catastrophe.
Look, if you're going to be hooking around town at breakneck speeds and regularly hitting 100mph somewhere or other...sure get a booster to provide you with a little more confidence that the car will stop. My point is that you don't need to go to that trouble and expense if you don't have to.
I've spent many years driving cars with ABS. When you step into a car without ABS, you need to re-calibrate your thinking. Back off, leave more room, drive slower. When you do those things, your need for extra braking assistance is reduced. Also reduced (on a Demon without a booster) is complexity, weight and cost. You have a cleaner engine bay and you have better reliability (because you have less bits under the hood that can fail).
