Having sold drumkits on Craigslist, Ebay, and Reverb, I'll throw in a few suggestions.
Craigslist-I'd try selling here first, or at the very least concurrently while you have a listing with ebay or reverb. Just be prepared to pull the item once it sells locally. I've had some negative experiences with Craigslist individuals early on....DON"T let them come to your residence(I don't know why I ever thought this was a good idea!). Try to just meet in a public place, even if it means packing up the kit into your car. At least you can drive off if you get a weird vibe or sense bs. I always give them my number and ask that they text me to confirm the meeting time. Save yourself a trip from the people who don't have the cash to begin with, or the general time wasters. Usually someone looking to do the legitimate transaction will follow through. When you list your gear I would always put a stated price in the ad. 99% of the time, the people who message you want it at a lower price than what you are asking. Don't put "best offer" in your ad because automatically you are agreeing to sell it lower than you want. Just let them throw out the first price and work from there. Sometimes, they won't even try to haggle over the price. If they want to see it first before the offer, chances are they are serious if they show up to meet and will make a reasonable offer. Be sure to state "cash only" in your text when they confirm the meeting place and time.
Ebay-use the "buy it now" and specific local pick up only. Yes, you will incur fees but if someone wants the gear, they have to pay first before you deliver the stuff(or pick it up). Once they pay, there is a low likelihood they will flake out and not show. Plus you are getting more exposure to people who might live in a surrounding city/town/state and are ok driving a bit to get a decent deal. I've met people at the half way mark.
Reverb-this one too has fees but its a much bigger market exposure than the local CL market. My experience is that you can get a higher price for your sale because typically you are dealing with musicians who understand values of specific instruments....as opposed to a parent just looking for a set of drums to start their kid out on.
With Ebay and Reverb-absolutely make sure you have boxes/container ready and have the shipping logistics mapped out. Using the UPS shipping estimator is a great tool and will help you save time once the item has sold. You have to be ready to ship if someone buys your stuff immediately. Buyers on Ebay and Reverb for the most part expect to get a tracking number within a day or so. Most of this stuff might seem like common sense type stuff, but you wouldn't believe the stunts people try to pull on Craigslist...I know because its happened to me. Hope this helps in your decision.
