I can definitely say you'll be satisfied with Vallejo.
A few pointers:
-Walk a fine line between thrifty and hurting yourself. If you're interested in this work you'll have to practice, but don't short yourself trying to save money to the point you can't enjoy learning.
-Make some of your purchases varnishes and "matteners" (the real name escapes me, but they function to take the shine out of paint). These are integral in adding important features like glossed, lifelike eyes.
-A sealant is optional but suggested. It will help hold the sculpt up to wear and tear. Make two notable observations though, the finish of the sealant (satin, matte, gloss, etc) and when and where to apply it. It's sometimes a good idea to make a "save point" and add a sealant as you later your paint. It also can assist in getting the skin tone in 1:6 right from what I understand.
