I had a big purchase through them recently which had me worried for a little while..I even started a thread like this.
I had good correspondence with them until I paid the money and then couldn't get any reply for a couple of weeks, during which time the order was meant to have shipped. I emailed the owner in the end and he said their internet sales person was having troubles sending emails to me.
They were very apologetic and kept me well informed from then on, but I got the feeling they had sold my item and were just waiting for another to come in
