I've been using a bunch of Kodak 5222 ("Double-X"). I got a bulk roll of it a few years ago, like 130ft for $20. Slightly expired but still pushes great to 400 or shot normally around 200.
Higher sensitivity and I'll go for HP5, but that is getting less common for me nowadays.
Hey, I just picked up a WEGA 32FS320 this week! It's my first non-Commodore-1702 CRT.
Now, if only I had anything that output composite or component laying around... gotta dig out my old PS2 or Xbox.
