If you're new to the technology, there's no hurry to get anything expensive. My first tablet was a 20 quid job from Tesco, and after bashing at it like that monkey from 2001 at those bones, I gradually got the hang of things. Plus, some of the bells and whistles on the expensive tablets can be a bit confusing - the touchpad ones can be a nightmare to use until you figure out calibration and touch-sensitivity settings, for instance, and also might require you to upgrade your video card. likewise, even basic models with good tech support might need a patch to run on Vista - like 99 percent of everything else on the market.
A good art programme is essential. No illegal downloading, though - if you can blow 50 quid on a tablet, you can spend a measly 800 nicker on a copy of Photoshop.
This would be the thread to ask, I imagine - does anyone have any tips for brush settings in photoshop? I'm trying to get something that looks vaguely like a natural brush stroke. I've adjusted stuff like opacity, flow, changed the brush settings to a mix of multiply, burn, dodge, normal, but it all just swirls together after a while and I'm lost at this stage.
