Looking for an application Decompiler.

Hey, I'm not really up to date with this, and have never really looked at this type of thing before, so if anyone knows of an Application decompiler and give me an idea on where to get one, that would be fantastic.
And if you really feel generous, a .exe decompiler would be amazing aswell xD!

Hex Rays decompiler
IDA Pro
I think that's the best you can get...

Google either .NET reflector or ILSpy. They will both decompile any programs developed in C#/VB.NET and give you the source. For programs coded in other languages it might be more difficult.
