Looks like Ms. Caldwell is a lefty, so her Macworld review could be helpful to you.

Thank you for the link for another poster (B.A.T), and thank you for the review, Ms. Caldwell. The review is the best that I've seen about the styluses. I wish all stylus reviews would be done with the same dedication and to the point -attitude.
My personal experience is of Griffin Technology Stylus/Targus (the very same pen can be had also with Targus label. That pen shouldn't be be confused with "Targus 2in1" -stylus, which is not the same pen). It was cost effective. I paid about 13 euros, and it works for drawing at least, as a lefty. It has a decent tilting angle.
Wacom's pen has got some good reviews and opinions, and it is on my purchase list. The price is a bit high, but that smaller nib can make the difference especially in writing and is important in pencil work too.
On a sidenote, that NomadBrush is an oddity, but a brush like tool is an interesting concept for painting. I want to check it.
But it is not about finding a good stylus only. The pen has to work together with a software. A minimal lag is essential for both note taking and drawing.
If one wants to take visual notes in a notebook-form, Wacom's Bamboo Paper is definitely worth trying. It has a nice feel of drawing with an ink. If one wants a weightier version, PenUltimate seems to be an option. It has some extras and essentially handles more that one notebook at the same time. I wonder if it has the same good or even better feel of working with an ink than Wacom Paper has?
And then there is at least one app, WritePad which tries to do a character recognition. Has anyone good experiences with that or other note taking software with recognition?
