Re: cencovspascoballisticpend.

My experience with the Beck pendulum is similar to Greg's. We got ours
between 1989 and 1991, and they have been virtually trouble-free, with no
need for any alignment tinkering. I am just approaching the point of
needing new racks so am glad to hear they may still be available.
Daedalon's website does show the pendulum itself
(http://www.daedalon.com/bbeck.html), but no replacement parts.

Greetings,
We, at El Camino College, are about to purchase 34 new
ballistic pendulums. We were originally going with the
old-style Cenco BPs when the new style by PASCO, were
pointed out to us in a catalog. Has anyone had enough
experience with both to comment on whether the pasco
type is worth the extra 140.00? The old style works,
but constantly needs tinkering.

Have you considered the Beck style? I believe they are still available
thru Daedelon perhaps? They seldom if ever need adjustment and only
require a new rack from time to time.
