So early this year, I bought an HP TX1000 PC and what sold me was the ability to use touch screen which I thought would be great for me to try and get into drawing. So when I finally get round to installing photoshop and trying to draw.... I realise that using it for drawing just plain sucks. Either I'm not calibrating it properly or something, I realise that using it purely for drawing isn't a good idea. Either way, I'm going to buy a graphics tablet but the Wacom ones seems pricey while the cheaper ones I saw are just too small. Is there any middle ground or recommended brand?
