I just paid about $35 shipped in 2 days from the Mother ship...slightly different model, so not a direct comparison. But mine has a power jet setting in the middle. It's like a lava hot massage right on my back, which is amazing after a long day.
Otherwise, 50 jets are still powerful. I got the 2.5gpm version, and will be drilling out the water flow restrictor in the stem, getting close to 4gpm.
...i remain, he who remains to be...
