Hey there, can anyone give me more info on:
-which range of Vellejo should be used
-the quality in comparrison to GW paint
-and the shade differences, can you get all the GW colours in Vellejo? and is the Vallejo Ultramarines blue exactly the same as the GW one?

"Which Range" depends on the application you need it for. There's the Game Colour, Model Colour, and Airbrush lines.

Obviously, Airbrush is for... well, your airbrush.

Game Colour is the parallel line to GW paints. The names are nearly identical, and the colors are nearly identical. Nearly.

Some are a bit lighter than their counterparts, some are a bit darker. Don't count on them to be an exact match - but a marine painted in GW Ultramarines Blue, and VGC Ultramarines Blue will look the same on the table, even if right in front of your nose you'll be able to see a difference.

Model Colour, on the other hand, is completely different. It offers a huge selection of "New" colors that aren't found in GW's very cartoony and limited range. There are a lot of Military colors, and earth tones - all very natural and "realistic" looking. They also have very high pigmentation, and will cover in a single coat - even reds and some yellows, over black primer.

edit-- while I am at it,if I can get testors dullcote, would GW gloss varnish be a suitable base... I can't get that many brands here so I'm trying to keep it basic.

I used to swear up and down by Testor's DullCote. And it still works really, really well. But Krylon has reformulated their "Matte Varnish" (1311), and it now goes on just as dead-flat as the Testor's always did (I used to not use Krylon, since the Matte still had some sheen - not any more!). So for the same price as the wee can of Testor's, I now get a full "man-sized" can of Spray Paint. Same result, WAY more economical.

And yes, it will certainly kill shine dead - even from a protective bullet coat of GW, or any other, gloss varnish. Just give the gloss a good 24 hours to cure before dull-coating it, to make sure you avoid any "frosting."
