Main Return Submersible Pump(s) Needed

[tzsetzse]

Looking to replace my Iwaki external with in-sump HP return pump. Mag Drive 9.5 or 12, SICCE or SEDRA in the 750+ gph range. Also, my skimmer pump's impeller imploded with no replacements available so needing a RIO/TAAM 2500 or 3100 for that. USED is fine as long as they are in good shape.

Thanks!
Don
