What we tend to see in these (and other onine sources) are the complaints, the small percentage of buyers who didn't read or understand the shop's policies. While I prefer to shop locally to support the guys who are going to be there wnen I run out of glue or paint, there are some lines not available here and some online deals are just too good to pass up .
Paypal is an excellent way of transferring funds. You can protect your privacy and funds through the use of a Paypal specific email address and a prepaid or low limit credit card. In the many years I've used Paypal, I've only had one bad dealer (not modeling related so the name is irrelevant) . The involvement of Paypal's dispute process got me a refund immediately. Using a check or money order, if these would even be accepted, would leave you pretty much high and dry resorting to the courts or postal fraud divisions involving several jurisdictions.
When I've sold on Ebay, I've only considered Paypal. The money is in escrow as soon as it is transferred and I can ship the item. With a check, I'd have to wait for the buyer to get it into the mail,for the check to be deliverwed, then wait for it to clear before I'd feel safe in shipping, making both myself and the buyer wait longer than we'd like to close the transaction.
With Paypal's method of funds transfer you are much safer than using a credit or debit card at a brick and mortar business. We've had our cards compromised a couple times right after a shopping trip. While we lost no money, it was a PitA to have to get a temporary card then change all recurring payments to the new number when the new card arrived.
Finally, as a friend of mine used to say, "beating this horse to a dead beat," LuckyModel's availability is pretty clearly stated:
