Check these two sources -- KEH AND MBP. B&H and Adorama also have used camera gear but the two I advised you to check have an easy-to-understand grading system and it is spot-on. If they show a piece of equipment as excellent, you can be assured it will be excellent or better. Use that as your guide. Consider those places are in business to make a profit and they have expenses in doing so. When you sell your equipment you do not have a storefront to maintain, employees to pay, or inventory to maintain. You do not offer a three to six-month warranty. Because of those factors, you cannot expect the same price they are charging. Depending on the condition of your gear you should expect to get between 15% to 25% less. Often they will have sales of 10% off which makes a reduction of 15% less attractive. If you want to move your equipment in a reasonable amount of time, list it for 20 or 25% less than KEH or MBP is listing it for. Here on the Hog is a good place to sell your gear. Most of the regulars here are honest and appreciate good equipment for a good price. Ask for payment through PayPal as this protects both the buyer and seller (use standard PayPal, not the friends and family). Good luck with your equipment sale and I wish you well. I'm sorry to hear the equipment is too heavy for you now and I hope you can find some that will allow you to continue your photographic pursuits.
