When I bought my first DSLR, back in 2006 it was helpful to be able to lay hands on the cameras I'd shortlisted. In fact it was a hands on experience that drove me away from the idea of a bridge camera and into the arms of the DSLR world at over 3X the price. But having chosen my path forward with Canon I have never since had need of a physical store for my photographic shopping. A further six DSLRs, maybe a dozen lenses, three tripods, studio lighting and all accessories bought since have been ordered online.
In approximate order of total spend, highest first, it goes something like this....
Jessops, by a significant margin, and all at very good prices relative to the rest of the market place at the time
Digital Rev and Warehouse Express vying for second place
HDEW Cameras
Elemental Studio Flash
Onestop Digital
Morris Photographic
Kerso (Flash Camera)
UR Galaxy (eBay)
Jacobs
Clifton Cameras
Miscellaneous eBay suppliers
No complaints about any of them so I'd continue to use them all (or those which still exist), although my needs are pretty well met by now and I'm trying to resist further spending urges. I've had occasion to need post sales support from Jessops, Digital Rev and Elemental. All problems have been resolved to my satisfaction in the end, but Digital Rev really dragged the process out when an order went wrong over the Chinese New Year period. Elemental were excellent. Jessops were about what you'd expect from a large chain with big corporate rules and impersonal service - box shifters in other words.
For future shopping needs I would certainly consult camerapricebuster for the best prices and then see which of my favoured suppliers could do better. Picking the winner for my custom would not come down solely to price, but also perceived service quality, reliability, convenience etc..
p.s. I did also spend a fair bit with
Park Cameras and Amazon on lenses but ended up returning them due to defects, fuss free, for a refund so they're not included in the list above. I'd happily use either one again, especially Amazon, having bought lots of non photo gear from them over the years.
