Ducane is not what it once was...as far as I know, DuCane is only a badge for some Chinese made grills that Weber now owns. I honestly can't say whether they are good or bad, but they are not the American made tanks of prior years.
About 2 years ago someone on ebay in the Chicago area was closing out some old USA-made stainless Ducanes and I bought one. Even with the $$ shipping I spent less than half of what they typically sold for. I use it 2-4 times per week year round and it has been great.
Bob in RSM, CA...yes, I know, it's a long way from Chicago
