The guys and gals at Reefwise are cool people, so I am sure you will be content with the water from them, but there is a lot to be said for having your own RODI unit, and making your own saltwater. I live in a tiny 1 bedroom apartment, and still managed to find room to store my water. Granted, my kitchen had a funny corner anyhow, so it fit naturally in there, but I'm just saying - if you can find space to store water you buy, you can find space to keep water to mix yourself. As far as the rest is concerned - it's up to you if you prefer lugging buckets around or not. I should also mention that cost-wise, RODI will win out in short order, the units really aren't terribly expensive at all in the greater scheme of SW tanks. Good luck with it all, regardless of how you choose to go about this, and welcome to the very fun (expensive) addictive (expensive) hobby!
