Hey Phil-
thanks for the reply-
I will try to find his post -it was on Motorgeek...(dahh - just spent 20 
minutes searching his thread and can't find it....oh well)
I personally have had good experience with the trusty F5DPOR - and I must 
confess it is all I have ever used - however when it comes time to replace- 
I will get crazy and try something else.  Having hard time accepting there 
are no good alternatives - I'm stubborn - my problem.

BTW where are you finding the F5DPOR for $11 - last time I paid $19.95. 
ouch.  That was through Mockry or TPC.
