Shundian or Suning, which is better to buy SLR?

At present, Shundian's digital cameras include entry-level, professional-level and high-end professional cameras, which are suitable for beginners, business users, photographers and professional photographers to meet the different needs of major photographers.

I just bought a SLR in Shundian a few days ago, just in time for "30 days dissatisfied with the original silver return".
