There's a whole thread on Whirlpool about it or just start a dedicated buying thread. It typically runs for fifty pages before concluding that for official warranty and support buy Harvey Norman, increased risk of warranty or other dramas buy elsewhere. Nuff said. Now... Merlin looks good but typically runs a little behind the official firmware when updates come out (understandably). But looks worthwhile. Wow one could lose a whole weekend tinkering with this thing which I will resist. I think I'll just set up Merlin and leave it at that for now.
