I'm not necessarily hung up on having silk ties, I just want ones that look nice and are put together well.  Look no further, the Scott Allan ties are not silk, microfiber but are well constructed and come with a tie hanger.

Pros:
  - Well constructed
  - Colors are distinct and vibrant
  - So many selections...

Cons:
  - Microfiber makes them pretty thick so you have to work to get them covered by your collar
