If you even bring Citniq into the discussion, I assume you can afford it. And if so, it's alot better. Most non-wacom vendors use a pen with battery (patented technology), it makes the pen very heavy, and if you spend hours drawing, it will be a pain. No matter the other quality. Also the crappy screens some of them got, and software for adjusting (etc, no per-program settings, don't recall the vendor for this one tho).
Wacom stylus are 18gr (and sorry, with an other battery the Yiynova is 19gr, I switched it just after my first reply)
It's heavier than a pencil but honestly, if you found THAT heavy I'm worried ^^ Propelling pencil and mechanical are often used for drawing, and they are "heavy" too, ink pencil, marker and so are not light either... If you plan on making art only with feather, you are not going anywhere. When you work with a tool, you get used to it, that's how things work.
I'm sorry it's definitly strange to say to someone "pay 1200 $ more to get a tablet with a 1-5 grams lighter stylus". Better not buy a digital tablet at this price
Lol two bad comments on deviantart don't make the Yiynova horrible. Issues posted here were about power supply issue, mostly. Honestly PandaCity is just great at customer service, they will help you and follow you at any time you need. They do not complain to give refund if you are not satisfied too.
The Yiynova is good, I have the msp19u, it work with almost all the art programs I tried except My Paint. For all other : photoshop, illustudio, painter, artrage... it work. They are some reviews on youtube showing it working with manga studio, illustrator...
If you check the amazon.com page, you will find a dozen of good comments about the yiynova, if you check more forums on the internet, other users are happy with it... When crap happen, it's often drivers issue or user mistake and there is always a solution about that.
Bosto is probably good too, but again it's not very famous arround here. I have no idea about customers support for it...
