I'm gonna paste an honest opinion of someone from the net, so right so funny
"When you're already competent artist, and can afford it somewhat easily. Don't be one of those guys that spends a shit load on your hobby thinking it'll make you more proficient. I see it all the fucking time. People buying $4000 DSLRs and putting watermarks on shitty pictures on their local park. People buying an Intuos Pro just because it's a fucking status symbol and they don't even grasp what "tilt" functionality is. And lastly, the worst, people who buy a fucking Cintiq before than can draw for shit.
Think of a Cintiq as one of those ridiculous aerodynamic bicycle helmets. Unless you're a pro where fucking milliseconds matter in your lap-time, don't bother wearing it."
Be honest with your skill set to guess if something like a cintic is out of place. You can update your old monitor to newer one, there are +22HD with same presures and color ranges like cintiqs out there. Huion, yiynova, etc.. Of course, do whatever you want,, guess about the rest priorities in your life, if buying a cintiq does not affect your pocket to react to incidentals, go on.
At best you should introduce yourself, what you do, where r u from, how old are you, etc. :)
