I bought my last from Warco, a few years ago and still going strong. I lashed out and bought a bi-metallic. The carbon steel blade that came with my saw worked well enough to prove the machine cut metal, but didn't last long. Probably about as cheap as possible to prove the saw worked out of the box, but not much longer! It broke at the weld and lost teeth like yours.
My band-saw was by far the worst of my Chinese tools, pretty crude throughout. It ticked when the blade weld went over the drive wheel, and cut sideways. However, filing off a tiny casting ridge on the drive wheel and tweaking the tracking made it cut straight without breaking the weld. The other important change was the casting didn't quite allow enough room for the tension adjuster to fully relax, putting a fair amount of stress on blades during installation. Filing a couple of millimetres off the casting fixed that too. My favourite tool now – not because it's beautifully made, but because it works and saves so much time. Can't remember the last time it needed attention.
