I just sprayed my ceilling in a new addition that looks wonderful. I was not concerned with overspray on the but I would probably never spray the walls. I use a spraytech 1620 apex 2. This is a great sprayer that cleans up in about 15 minutes. Whatever you do post some photos. Good luck
Home Depot held a special on the Graco X5 a while back, and I was planning to paint my basement ceiling in flat black at the time. Picked it up, had absolutely minimal experience spraying (but about 8 years brush/roll application experience), some helpful guidance over the phone with a painter friend of mine, and the outcome was far better than I'd expected.
I know you're not interested in hearing the "how tos", but I'm going to anyway. lol My advice is if you have a painter friend with experience to talk you through it over the phone or to come by to show you how to get started, you won't be dealing with as many headaches. Getting the pump ready for paint isn't nearly as much of a pain as it is cleaning it up, which essentially for the sake of any future use is the most important part. Walls I found were the most difficult, especially any smooth surfaces. You have to keep a consistent follow through, otherwise you'll have runs galore. Also, buy lots of visqueen and drop cloths to cover anything you don't want to get overspray on.
Obviously because I'm a noob in spray application, I don't have any experience with Titan, but I thought the Graco was a nice sprayer to work with. So I'd say go for it. It's your home, no better place to learn from your own mistakes. Good luck!
