Gas tank, Repair or Replace?

As some you have read on Polaras project thread, I'm having a problem with dirty gas.
The tank needs be removed and cleaned or replaced.
In addition to the old gas, the stock tank has a soft ball sized dent on the driver's side.
The sender seems to work fine.
A new tank is about 4 bills with freight. I figured a new float and sock along with gaskets and a tank to trunk gasket too.
Thoughts? Opinions?
Thanks
