I recently purchased this spa on E-Bay for $2,350.00. I added stainless jets-this was a $295.00 option. Received the tub, and ony the rings around the jets are stainless. Also the largest jet is plastic. I have been told that stainless "ringed" jets are the industry standard and that the plastic jet is too large to be stainless. Too late now, but, was this a rip-off upgrade and also does anyone have any feedback regarding this spa?
