I want a new bathtub! Mine has a couple of hair line cracks in it, and I have had it repaired 3x. When the house was new and had a warrenty on it, they said "oh its fixable" let the warrenty expire and they said "oh, it needs replacing." I would replace it with a jetted tub.
I would use the extra to buy a pellet stove, and get new counter tops. Mine are dark and ugly. not bad shape, just ugly.
I spent that kinda quick.
