As Terry has hinted at, paint is very much a personal preference kind of thing. There are way to many things to consider to be able to give a good recommendation that you will agree with.
Practicality: What can you get hold of easy. Not a lot of point in finding out that the paints you want to use are not available/close by.
Which type: There are Enamels and Acrylics. Some of us love Enamels and others Acrylics. There are restrictions on sending enamel paints in the post in England and I am sure that the "clever people" in the EEC/EU/what ever they call themselves this week would love to get them banned.....thats another story.
Ease of use: All paint types are easy to use. Its the cleaning up that the big difference bites you in the rear. Enamels need turps/white spirit to thin and clean. Both pong and cost beer tokens. Acrylics can (I wouldn't advise it) be thinned and cleaned up with water a la tap. Though it is better to use distilled as there is no chunks of chalk in it to clog up the
airbrush you soon will be buying.
Also brush or Spray. Some paints can be used with either, others can be an either or.
Enamels brush very well and spray even better but they smell and take a long time to dry.
Acrylics can generally be brushed or sprayed but there are some that are not very pleased with brushes. Vallejo
model Air is great for spraying, but can give problems with a brush. Their
Model Color range brush very well and spray very well after thinning. and best bit quick to dry and don't smell!!!
As you can see there are many things to consider and I have only touched the surface.
My advice; see what you have close by or are easily available, try a few and see what you like the best.
