I'd be rotten too, having just bought it.
When they were in business our experience was that they couldn't do enough for us. I think Dons still answering his phone or at least he was last week, he said to me he was still carrying out basic remedial stuff as a courtesy in sydney. He also runs a solar light business in silverwater as well. Maybe see if he could help as a goodwill gesture, he's a pretty reasonable bloke, its hard as liquidation is liquidation i guess its the last thing they wanted as well.
We've had our CT for nearly a year now, there were a few issues we had to sort out straight after delivery but now having had it for a year or so their pretty rugged things with not much having gone wrong with it and we take it out at least every 6 weeks.
Really hope it works out for you.
