Thank you Evan.
I appreciate the help. That thread answered many of my questions.
The only thing I still don't know and would like to is how long Ben will be offering that "upgrade price" for these new kits.
I do not mind upgrading now to the PS234, but my PS232 is working fine and I bought refills for it not too long ago.....(I think last year around this time).

Thanks,
Frank D.
