I've been thinking about selling some gear
here but never have before. Just wondering
if I could get some pointers about how to
go about it.
My main concern is I don't want to get
scammed.

Generally, the risk is on the buyer isn't it? You hold the gear until you get the money. Never accept a personal check for starters.

As a seller, this is a great place. I have sold several things to members here, and also bought some. When buying, as long as person has been around a while, no problems. When selling I always take paypal, ship only to confirmed address. Your risk is pretty low since you have money before you ship.

There is a small risk to Paypal... see http://www.paypalsucks.com/

5. If you are a bona fide, up-standing individual with hundreds of successful transactions, but someone pays you with a stolen credit card, your account (by PayPal's own admission) is immediately flagged as being "criminal behavior" and any money in that account is confiscated. If a customer "disputes" the charge, same thing happens. (See email above.)

Of course, there are other risks that could happen:
Mailman can't find the address. (Happens to my residence.)
In person transaction- you get hit by a car. It can and does happen! You just don't worry about it, and it probably doesn't make sense to.

Generally, the risk is on the buyer isn't it? You hold the gear until you get the money. Never accept a personal check for starters.

So maybe like a cashier's check? I have read
somewhere recently that some scammer even
made up some fake cashier's checks. The seller
deposited it in his bank account and shipped the
items off. Later the seller's bank notified him that
the "cashier's check" was no good so the seller
was basically out of luck.
Would you all agree that's it's reasonable to
request a cashier's (bank) check and wait for it
to clear before shipping?

There are some cheque and money order scams out there.

Normal cheques can bounce.
Some cheques from London banks will clear at first, then they will say you have been duped.

Some people report fake money orders.

The following website has some interesting info:

2- One thing that you can definitely do is to protect yourself against "phishing" scams, which are probably the most likely scam you'll encounter.
Example:
You get an email that comes from paypal.com and links to the paypal.com site that says you need to update your account info. The email is spoofed and doesn't actually come from paypal.com, and the links don't point to paypal.com (they are taking advantage of an IE bug). Basically... the company should never ask for your password or account information.

I don't think it would be completely unreasonable to hold the item until your bank verifies that the cashier's check has cleared. You should let the buyer know before hand though. I recently sold a mic to someone on these boards who posts regularly and felt perfectly confident in shipping the item as soon as I could deposit the cashier's check. That's probably the best safeguard.

So what do you have for sale???? :)
