Hi Unisys,

I saw some inferences to differences in the '98 and earlier versions of the CD4E, and was wondering if you could shed some light on them, as you seem to have researched these quite thoroughly.

1. Are there differences beyond the pump design?

2. If so, what?

3. Are all 98-on ATX's equally strong, or are 98's the best choice?

Thanks for sharing the fruits of your research with the rest of us...
