Ron, you beat me to it!!!
All I'll add is that - in drag racing circles at least - I know personally of a number of guys that gave up on their Jericos after breaking second and third gears repeatedly. They haven't looked back after going with G-Force. I really didn't want to have to spend the $5K unnecessarily, so I've spoken to guys about Richmond / Doug Nash, Liberty Toploaders, Holingers, Hewland, Quaife, Getrag. The drag racing guys will universally rate G-Force as well above Jerico for quality and strength. The road racing guys have to spend $10K to $20K to get a similar shift quality out of a Holinger/Quaife/Hewland. The G-Force is rated to handle a higher torque figure than any trans I'm aware of (short of a Lenco - which you cannot downshift...)
To be fair, I did read an article from a year or two ago where Billy Glidden claimed that he didn't like the G-Force gearboxes. So there, you can't say I'm being one-sided now
