Greetings,
I was having to replace the cartidge for yet a second time in a bit over a year.
My question is this....This is the exact replacement cartridge.

http://www.lowes.com/ProductDisplay?...llow&cId=PDIO1 price around 40 dollars.

I also see this one, and seems it might fit.

This one is around 9 dollars.So my question is does the 40 dollar one cost that much because its a temp control one? and i could replace with a cheaper one and not car about the temp control part?
Thanks in advance chopped
