How important is factory ballast when buying a used V-drive?

I'm looking to buy my first wakeboat and have been looking at v-drives from the early 2000's. Obviously prices are lower on boats that don't have factory ballast built in. I never had any experience with wakeboats growing up, and always wakeboarded and skied behind an inboard/outboard. Of course, I'd like to get a boat with factory ballast if I can find one for the right price. My question is how much of a pain is it to add and use ballast (either fat sacks with manual pumps or an aftermarket automated system) on a boat without factory ballast. Is the higher price worth having factory ballast for convenience, performance, space, etc.? Thanks for any input!
