For me it was D-gray man, season 1 part 1 about three years ago. Since then i have been mostly buying funi shows.
I've been collection anime for 11 years now and I have 1,029 DVDs and 2 Blu-rays (just started collecting Blu-ray) according to my database. Out of that number, 323 discs (321 DVDs and 2 Blu-rays) are from Funimation.
i bow down to your otakuness (yes i know thats not a real word) good sir.
