I've placed two orders with these folks recently, with outstanding service. I emailed them on Sunday evening, got a reply within an hour, PayPal'd before bedtime, got a confirmation email Monday morning, package in my box on Wednesday. Come to think of it, the first time I ordered from them happened to be on a Sunday, too, and they replied the same day. What twisted kind of vendor answers emails on a Sunday night?
