I bought a C1K from Conics too, in March 2005.
Paid w PayPal and there was no problem - the initial price estimation was very close.
I preferred to go with Conics for two reasons mainly:
1. it was well 'reviewed' in these forums.
2. considering what I got, it seemed like a good balance between price and choice of accessories: the USB host cable and the PSP power adapter (110-240V)
The service was excellent, the website was clear enough for me and the email was very prompt considering the time zone difference.
It took less than a week from Japan to US, but I had to wait a day because of the post office...
Brett did the english conversion and that was all I needed to get started the first day - other than recharging the battery of course. I just didn't want to wait to read any more, do the conversion myself etc. Plenty of time for that after the initial excitement.
It is my first Z after all...
microsoft/linux,
personally I chose them over Streamline (in addition to the reasons above) for the fact that C1Ks were not in stock at the time (pre-order) and I knew Brett had a history in these forums - no offense meant to the Streamline guys. I also looked a lot at conics.net when I was trying to decide if I wanted to buy one or not.
Overall, I was very satisfied with the service and I would recommend Conics without hesitation.
