Best rail ticket website

The smart money is on www.nationalexpresseastcoast.com despite its name it covers all National Rail, not just its own bit. A nice interface, good at picking cheap fares and even has a system for letting you know when booking opens. Copes well with railcards and lets you reserve cycle space though I had problems with this when buying a special low price ticket. It automatically reserved me a seat (no problem) but then greyed out the cycle reservation option, which it wouldn't let me take before I'd picked the ticket. I had to phone up the rain company and reserve the space (they did it well without fuss) but NEEC need to fix the bug.
