I was concerned about how well the plastic would hold paint, as it's a little bendy.  Turns out it holds the paint excellent.  The mini's come painted in a flat colour (grey for germans, green for yankee dogs) and whatever spray they use binds to the plastic really well.  I re-primered my test guy just in case, but no real need.  I use grey primer so the Germans are ready to go but I will prime the Americans as I don't like painting over that green they used.  I painted this guy as he came right out of the box, so you can see the bend in the barrel and the mold lines on the mini.  For gaming, I think it's more than acceptable.  The paint job is no great shkes but it was done quick (maybe a couple hours) and I think will work for the table.  Even though the mini's are wearing winter style uniforms I decided to paint both sides in a more sort of traditional WWII outfit so I didn't have to tie myself to painting all my collection in a winter camo scheme for as long as I collect the game.  It'll look a little odd as some mini's are CLEARLY wearing winter coats.  Anyway, here's what I got with a straight out of the box mini and a couple hours...

Things I found painting this kind of plastic...
-Be careful with the hairdryer!  As I was painting quickly I used the hairdryer quite a bit.  At one point the mini got pretty soft.  Watch out!
-The base.  I was stuck thinking what I could do for the bases.  They come with a sort of metal industrial texture to them and a sort of stylized bolted down rivet look around the edges.  In the end I decide to just go for a plain black base.  I can always come back to this but it'll work just fine for gaming I think.
-The torso's all come joined to the legs so you can twist the upper body at the waist.  I just superglued them in place.  I don't think this has ay relevance on game play at all.
So that's it.  A little mini report on what I found so far.
