I would also look at HD/Menards/Lowes for a new one...deep freezers are something I wouldn't want to buy used or find out someone else's problems. Is it worth saving 50 dollars? Plus you'll have the new energy star model.
I would go either Sturgeon Bay or Algoma in the summer for salmon. Depending how late in the fall you want to go, you could do Milwaukee Harbor for browns, lakers and salmon. How much lead time do you need?
