The 407 is OK, not great; 707 is much better (well worth the price difference) but it is a heavy style of cab which requires aging. Those prices are average, even for the US (I know a restaurant in FL that serves Bin 407 at $26/bottle!); thank you for the offer but it doesn't excite me. At the moment my interest has switched to Grange and to the fabulous for the price St. Henri Shiraz.
Sake is very tricky to recommend, there are tremendous nuances and variation ... also the pricing is much less rational than for western wine (price and enjoyment are loosely coupled). But a corollary to that is some very cheap sake can be very good (as with most Momakawa labels). Their infused sakes are also fabulous (very non-traditional but superb).
