This is a posting I saved from a while back and have re-posted a couple
of times. Seems the topic resurfaces periodically on this list.
Enjoy!

> The advantages of the Bosch are:

> Performance - I won't bad mouth the Lucas unit here, it lasted 24

> Price - I got a rebuilt unit for $20 less than I could a Lucas for.
