I dealt with Kirbans recently, and they were fine. However, I hate the fact that they ship UPS, which charges huge brokerage fees, etc.
I recently also purchased some GN stuff from another vendor, and they shipped through the mail. No fees, and it arrived in a short time. I wish we had an option of not using the courier companies. Not only are they way too expensive, they also deliver it to your house (when you arent home, of course).
Give me the good old post office, any time.
