We're more interested in service and personal treatment than saving the last possible nickel. Over the years we have grown to trust Calumet
for the vast bulk of our studio equipment and supplies. Yes you can buy the same brands elsewhere and often cheaper, but do any of those outlets have a living, breathing PHOTOGRAPHER available to discuss your needs and help fine-tune your options and purchases? I'm yet to call there and not get informed, professional advice immediately, or by prompt return phone call when the relavent employee is tied up. That's worth any price difference to us, and we've never found any reason either to distrust the advice or regret the purchase.
If by "reflectors" you mean those to go around your light, try this
page. It's the first of nine pages of them. Browse their site, and I think you will find them to be pretty well equipped for most of your needs- a nice complement to the good advice available over the phone.
