I want to buy a SLR in Macao, and I plan to buy it second-hand. Is there a reputable shop?

There are basically no well-known second-hand photographic equipment stores in Macao. Shops selling first-hand photographic equipment in the market are also difficult to meet. Don't hope that the tax-free policy in Hong Kong and Macao will bring the low price of SLR cameras. According to my experience, you can't buy a SLR camera cheaper than Chinese mainland in Hong Kong and Macao with a group tour. It will be cheaper to buy some unpopular lenses and original flashlights.
