Look in your local classifieds for an airless sprayer, Graco is the best option (last forever). Spraytech is alright, though they can't really pump heavy materials all that well (have one of those too), though I sold my Titan and kept the SprayTech (don't care for titan). HVLP systems are slow but produce great results (again, Graco, nothing under a 3800 for latex), however they are difficult to use if you don't have a lot of spray experience. I.E. after 10+ years of using an airless, I bought an HVLP for lacquer, and it took me weeks to figure out how to use it properly. If you have money to burn, you can't beat a AAA, again, Graco, the 395 finishpro model @ around $3000 (got one of those too) - best finishes i've ever produced.
But you could find a good used pump in your classifieds for anywhere from $200-500 depending on condition. Just stick to the brands or you'll just be throwing your money away. Whatever you end up with, get a Graco gun so you can use their fine finish tips.
As for coatings, that depends on who you have available. Here, I have GP, BM, Cloverdale, Acroma, Richelieu, and some others that I never use. Best cabinet coating you're going to find in a latex is "cabinet coat" by Insulx. For the best looking finish, use a pigmented pre-cat -- I use Valspar, Lenmar, Mohawk, or MLC. Trick is in finding the company who can do the best color matches for you.
