Haven't seen a fake one since they came out. Should be pretty safe. 

I'd say the Ultrasones or DT770.

For IEM: Definitely RE272.

Have seen them around the price a couple of times now. 

Might want to look into HF5, Re0, and RE400.

Amazing deals~ Want to try the beyers.

This is quite surprising at how many people can tell. Wonder if it'll be the same if its 320kps.

I want to try this so bad, but not time.  >.>

Here you go~ http://www.youtube.com/watch?v=OhnXUQRQ4u4 Really easy to do. 

I had the Fiio E6 a short while before the E11. What I can tell you is that there is a HUGE different between the two. For merely only $20 more, you can get the E11.

DT770?

^Agreed RE400 probably the best sub $100 right now. 

I've check the trade forum but couldn't find anything. I've also try the re400 but it is just not the same, it lack the energy the re0 had. Looks like my best bet is to email Headdirect. Thank you everyone for the help. :D

Does anyone know where I can get my hands on RE0? I've try to search various websites over the past months. Would anyone be kind enough to point me to the right direction. I take both used and new.
