they have a decent interface and seem to be having decent policies.
IMO e-gold interface s**ks badly. you feel that u r at some spamming / hacking website after u enter e-gold. therefore i have never been able to trust them.
in domain business paypal is preferred
so it would be hard to tell a potential buyer signup for an account at moneybookers, wait for credit card verification etc.
wire transfer is good for $xxx or higher valued domains
PayPal is more popular but I think that Moneybookers is the best. Small fees, very quick transaction, nice interface and very lucrative wai to solve issues.
