Just saw this Humax 500GB PVR on sale at Good Guys (And surprisingly enough, also on sale at Harvey Norman).
Usually sells approximately $350 I believe.

Quite a good PVR from the reviews i've read, especially for the price.
*Good guys mentions the Wi-fi adapter in their listing, so i haven't confirmed but it may come included. Might mention at Harvey Norman to get it included potentially too.
*Listed the expiry as 8/12/13 which is Harvey Norman's expiry. Unaware of the Good Guys expiry.
Keep in mind this model is 2 years old and the 7510 is available now/soon (just pre-ordered from Harvey's)

Biggest issue so far with new one is the "clicky" remote control but it has more DLNA and online features than old one. Also new one should have wireless adaptor in box for free.
I ordered it for $410, just need to paywave some gift cards now :P
