Power/Manual Brakes?

I'm stuck on the fence on what I should put in my 1968 Dart GT with Kelsey Hayes discs in the front and 10" drums in the rear. I used to have a GM aftermarket PB unit on there but took it out because it was a cobbled up mess. Now trying to fix the problem I have half my friends telling me to go power and the other half telling me to go manual. I currently have a new NAPA MC for a 1980 Dodge Aspen in my possession and was thinking about just fabbing mounts to throw that in there. However, an old auto tech from work is telling me to just go back to power brakes (more pricey) and fix it close to stock. I do plan on going to front and read discs within the next year or two. I need some more input from the specialists. Thank you! :D
