ok so photoshop is too much effort with a touchpad and my mouse is a load of toss. time to take the plung and purchase one. taking into account that i have never ever used one ever, i have no idea what to look for, ebay seems to tell me i can pick one up for about £20 which is fine by me. but something tells me they might be bollocks. so any help would be great. fire away knowledgable ones!
