Rich - I think most powders are controlled suds now. One exception I'm aware of is Era Powder, but recent uses of P&G and Sun powders (Surf, but not All) seem to make suds much less than their counterparts of a couple years ago before they were compacted.
I think in the move to make more and more detergents cross-compatible in HE or non-HE machines, we'll be seeing less and less suds from powders and liquids.
My Mom used All for years and years for its controlled sudsing with our water softeners, until Fresh Start came along, and then she still bought All from time to time.
