Shower Heads

I (Soren) have tried a few sub-2.0 gpm shower heads and really like the one that was given to me as a gift.  The trouble is, I can't figure out how to get more of them!  It's a Delta and has four aerated jets which produce a wonderful spray.  Yet is only consumes 1.6 gpm!  The only bad thing is that some water drips off the bottom (due to not exiting cleanly from the jets) even shortly after being cleaned.

I also tried a single-jet aerated Delta model (A112.18.1?) from Home Depot ($17) that was also rated for 1.6 gpm.  It didn't drip and it could keep you warm with just a trickle (one jet means a trickle goes pretty far). The downside was the it made noticeable noise (like a distant airplane engine) and it cause the air to move around a lot in our shower.  That meant that the tail end of the the extra shower curtain we use to put a "top" on our tub (think improvised shower stall) would sometime blow around annoyingly.

Finally, we tried a $20 1.5 gpf WaterPik EcoFlow from Target.  It had multiple settings and included a cut-off valve (we successfully use the $5 -- Home Depot -- cut-off as a temperature-insensitive variable valve to minimize water use).  The EcoFlow gave a pretty bad shower.  It didn't aerate so the flow was anemic (I also measured it at more like 1.4 gpm than ).  It was also somewhat flimsy and just unsatisfying.  After I gave Skander a similar one, he ended up with the same 4-jet Delta ... again a gift from someone in the industry!

Consumer Reports rated Shower Heads in August 2009 ... could the RP4634 be one of the ones I tested?
