I agree with you on it not being the best fit for a manual tranny. I had the same Logitech in my old Caddy with Joy2Mouse also.

I had to increase the mouse speed for the 8-way hat to be usable for mouse control, luckily the logitech supports differential mouse control (the longer you hold it in one direction the faster it goes). The buttons and button combinations got awkward as I added more and more functions. Lastly, the stock stalk location was a little off for my sitting position. I can understand how shifting gears with this thing could get old fast.
I upgraded the Caddy to a Saitek X-52 - more buttons,more hats, more programmability, EXTREME COOL FACTOR! and I don't shift often.
My Mustang has a CH FighterStick.

I designed it specifically for ergonomics after the lessons learned in the Caddy. In it, I cut off the stock stalk. And had a local metal shop cut and bend me a 1/2" round Stainless steel rod to fit the shifter and joystick. It may not be comfortable for others, but it fits me perfectly (height, distance, throw, angle, etc). When I drop my arm on the armrest, my hand naturally wraps around the joystick - a perfect fit. And the amount of available controls is excellent. My gal even knows which switches change songs and uses it from the passenger seat to prevent fingerprints on the screen.
There was a post back in 04/05 where someone modded the fingermouse onto a shifter. I had considered it for a minute but the fingermouse I had got all gummed up from dust and dirt so I decided it was no good for the car environment. Its internal wheels eventually had intermittent contacts and after less than 6 months daily use stopped touching the ball all together.
