Now you're talking!
Bit of a Sav Blanc girl myself.
Yep Villa Maria & Longridge - Jodie & I have sunk many a bottle of those together

! & if I'm pushing the boat out Mudd House at $20 (but its on offer in Pak n' Save this week for $13.95!)
If you're looking for cheapies - Timara is made by the Montana people & is usually between $7-10 a bottle & Rueben Hall is usually $8-10 a bottle. I quite happily drink these (we used to drink a lot of Oyster Bay & Montana in the UK but Oyster Bay for some reason is more expensive out here than in the UK).
If you're into desert wine then Selaks Ice Wine is lovely (I've downed many a bottle of this with not much help from anyone else!) at $13
