I've always had good luck with the Pilsen Avangard Malz Premium that Adventures In Homebrewing carries as their Pilsner malt selection. It's an excellent base malt for a lot of different recipes.
Favorite nostalgia beer....Stroh's original recipe. Every now and then you can find it here in Michigan, but for the most part it's as elusive as Sasquatch riding a unicorn, touring in a rock band with Elvis and the Loch Ness Monster.
