Being an overseas buyer myself, i've met quite a few turn downs for shipping cues to me direct so more often than not i have to turn to asking for favours from friends in conus to help out.
For me, i prefer to deal Paypal. Reason is simple, cos it's very very convenient for me. Takes all of 2 minutes to log on, insert email address of payee, confirm amount and click send money. Because i don't have the option to send money as gift or even the option to absorb the 4% paypal fee on my end, i usually discuss this fee option with the seller and for most parts i absorb them.
Being in China, bank wire is a bi*tch...there's very strict control on money going out even more so that i'm a foreigner in China...so i don't do that at all unless i absolutely have to but i haven't done so to date for cue purchases. Also i have no access to W.U, if i do then i might consider that option but only to very reputable seller.
As for shipping, since China will charge atrocious taxes for incoming products any cue that comes to me must be valued at $100-$150 MAX and only shipped to me via USPS. UPS, Fedex, DHL...any famed courier service for that matter will always get me taxed....somehow the local government have it in their hand that anybody who is using cheap international shipping (USPS) must be shipping cheap stuff so the customs don't usually bother with the items. But send a cue declared at $100 via DHL that cost $100-200 to ship and something's wrong...
Since i'm the one that requested for no insurance and low value declaration, i always tell seller that i am 100% liable for if something happens to the shipment. However i tell sellers in advance to practice due diligence in prepping the packaging to make it trash proof...Same goes for anything with ivory, anything happens to the cue and it's all me.
Being overseas i know i need to bite some losses and take more risk so i guess that's just part of dealing.
Going back to Mike's question, i'd say since he is the seller he has every right to turn down any deal that don't make him comfortable.
