I have included pictures for your reference to illustrate what the equipment looks like. The pictures, if clicked on, link to Amazon sites. I included these pictures because the pictures are good quality, free, and save me time. My other reason for using Amazon is that I specifically link to equipment that I would recommend buying and Amazon has consumer reviews and product descriptions. I am not recommending that you only buy equipment through Amazon, although I quite often use them. Any proceeds made from these links I will donate to www.worldvision.com, one of my preferred charities. I tend to use the UK Amazon site because they will ship more items internationally at a lower cost than the US site but some items are only available on the US site.
