There are a lot of things that I'm happy to buy online but expensive photo equipment is not one of them. Calumet have always given me great advice, and their test drive programme that lets you test equipment before buying means that you can buy with confidence, knowing that the tool does what you want. Buying from the same place as I rent equipment from is helpful because I get to see the same staff and know what I'm getting. Their prices are also excellent and I've not paid any more when buying through them than for the same item from my previously preferred online retailer.
