That's a tough call for me because I can find decent sheetmetal somewhat easier than you can in the east, for less money. However, I know for a fact that time is money, and buying a tub that may only need 50% of the overall work done, can save so much labor time, as well as materials, that a $3K price can get eclipsed quickly by trying to save some up front.
