These are a few merchants that I use and are very reputable. I use them and refer them with complete confidence!
Camren has a great selection of equipment for rental. It’s a great way to try something before you buy it or for those times when you just want to play. Very Fun!
Reed Photo is one of the most reputable printers that I know of. Great quality and prices that are VERY competitive. They are always friendly and helpful.
For used gear
KEH really does set the bar very high for used equipment. Everything I have ever ordered has exceeded my expectations. They also warranty their equipment so that you have peace of mind when you order from them. Definitely worth a look.
A great local retailer for both used and new equipment.
For new gear
One of Denver’s greatest photo stores for both digital and film equipment. Be careful, you’ll feel like a kid in a candy store.
B and H Photo is the best on line source for gear of all kinds.
You name it and they have it!
