I've been very pleased with the tankless. It cost about $400. on line, but I had to have some plumbing and electrical work done that ran the cost up. Had to run a few feet of smaller pipe, then have heavier gauge wiring and breaker in$talled.
I've found there is as much hot water available as with conventional tanks, except it never runs out and turns cold. In the North, you would need a more powerful one than I have.
