Having trouble with my Promatic 2 shifter... Ideas???

Thanks guys...was looking at a "Hurst 3838500 Pro-Matic 2" complete used gently for $80 on Craigslist.
He claims no problem using it for him.
Why is he selling it.
No, thats a question, if he likes it why is he selling it?
I kinda want to move to the floor but don't want to bounce 200 times, and replacing the 5' with a B&M 3' ($ range from $44.95 to $99.99) would be ....cost effective? ($285.70 at Hurst website)
Yeah, on the other hand I ain't young enough for the bounce, would be an overnighter, and column shift is fine. Now watch the guy want $40 for it and I'll find some kid that needs $10 to sit and shift so I can lay in the driveway all day-nap included- and play cable dog.....I'm talked out of it....for now, I'll have questions if it becomes one of those 2 good 2 B passed up things......Damn Craigslist....
