Went to Parkmore Kmart in Melbourne last night and they at 25% off all stock pots. Stainless steel, but thin with only spot-welded handles and no reinforced base unfortunately... metal lid. Largest size they had on the shelf was 15 ltr.. which discounted to about $15. Not many left, but might be handy for someone making kits.
However I went to Southland Kmart the day before and they didn't have any discount so it might not be everywhere.
I was about to buy one, but thought I'd have a look in BigW in Parkmore while I was there.. picked up a 19 ltr stainless (same quality but with glass lid) for only $20. If it only lasts a year doesn't matter, get another! Hopefully won't burn the wort though with such a thin base, just have to be careful.
