Here's a tip: Paint easy stuff first.
That means wooden things, zombies and space marines with helmets, terrain, that sort of thing. Doomed might be a good game to start with, based on that.
I paint to advanced tabletop for gaming.
Skill = time * practice more than materials.
For cheap paints, I would go with:
* Craft paints: Three browns and three greys for terrain and wood things.
* Hobby paints: Buy what's on sale. You're not a genius artist, so more fancier paints won't help you. Amazon has low prices for Vallejo Game Color.
* Washes: Make your life easier. Army Painter Ink Set. Never on sale, unless Miniature Market has sale on accessories. Go subscribe to their newletter yesterday b/c you've already missed deals.
* Brushes: Get a pile of cheap synthetics from Amazon with a 00 tip. Practice brush cleaning on them before you try out and ruin a $15 brush.
* Wet palette: Find a tutorial to make a cheap one.
* Mold line: X-Acto blade. Regular one
* Gaps: Vallejo plastic putty in a tube.
* 005 black pen: Eyeballs.
* Black brush pen: Assembly line touch-up of bases after the first coat of black primer.
Next:
* Hobby Brush: Do your research. Get one later than sooner.
* Styrlenezt (sp) paints from USA Airbrush. Get on their email list for their 30% holiday discounts. You'll be put off by their minimum order for free shipping, so just use regular primers for now. But they're sold in larger bottles, so, per ounce cheaper than hobby paints. Ebony Brown, Metal, Neutral (khaki), Flesh. Maybe red brown, grey, black and white, though white has too many bubbles. Other colors you just don't use as much, so I dunno about recommending them (red, green, blue). Gold, brass, copper have terrible coverage.
