Reflector replacement
ILSpy is the best reflector replacement I've seen yet. True to the original Reflector, it's light, simple and fast with no bloat or licence requirements. It shows you derived and base types in the main tree, symbols in the decompiled code window are hotlinked, and C# and IL are supported. If VB is, then I'd be glad to hear it, but it doesn't look that way. Ho hum.
Enjoy
