Photoshop Cursor ... any plug-ins to make it more visible?

I use Photoshop (CS, Mac OS 10.2.8) all day, every day. Specifically, I use it with a Wacom pen/tablet while I draw (mostly black and white) illustrations. But lately the cursor has been making me mental.

I use the “brush size” cursor (so I can tell exactly how wide my brush/eraser is), but I often have to click over to the caps-lock “precise” crosshairs because that little circle is so difficult to see. …But then I can’t tell exactly where the edge of my brush is, so I’ll end up erasing too much of something … and have to click back … but I can’t see that other cursor … and so on.

Is there a plug-in or something that could give me a more visible “brush size” cursor? Specifically, I’m thinking one that would invert the ENTIRE circle (or whatever tip shape) rather than just the one-pixel-wide outline of the circle, as it does now. Or even one that makes the whole brush cursor red or green or purple or something. (As I said, I work mostly in black and white, so I don’t care too much about obscuring the color behind the cursor.)

Anybody? No hardcore Photoshop geeks here?

Photoshop CS2 gives one the option of displaying both the brush size and cross hairs at the same time. Of course, that doesn’t help you at all.

(CS2 also allows one to view either the “Normal Brush Tip” or “Full Size Brush Tip”.)
