Rebuilding and reinforcing the bucket on my JD 2240- gave 20 years of good service but worn through in spots. Plan to cut out the places that are thin or perforated and weld in new steel. Thinking of springing for a plasma torch since cutting with grinder is long and expensive. So far, I see 35-40 amp Chinese models from HF and Northern tool between $500-700 and then much more expensive Hypertherm or Thermodynamics or miller up to $1500-2000. Any thoughts that I would be wasting my money on the Chinese ones (Chicago and Klutch) respectively? I've been looking for a used US model but no luck so far. Thanks
