I just finished watching the 'Twin Peaks Definitive Gold Box edition' (buy) set, complementing it with a viewing of 'Fire Walk With Me'. Been a very Lynchian long weekend. The Twin Peaks box set was an absolute treat, and I happily endorse it. For a 10-disc set, I also think it's good value - like $2.75 an episode, with the extras (of which there are many) for free!
On the Twin Peaks theme, here's a track by Mister Hopkinson's Computer with The Audrey 3000™ - a cover of 'Falling'.
