Decided to try DE last week. Ended up at Sally's after trying 3 other places. Since I was experimenting, I didn't want to spend too much. The friendly young lady behind the counter sold me a Chinese TTO for 12.99 and 10 Derby Extras for 2.99. The derby pulled slightly the first few strokes but got better with use. My wife found my Grandfathers (Great-grandfathers?) 3 piece Gillette so I tried it this morning. Experiment successful.
