Ya I tried the cart option once. I had a technical issue and they sold out before I could check the maximum amount that I can check out with. And this is a large undertaking for me, so I definitely want some certainty towards miner availability--for the initial purchase and reinvestment purposes.
About Canaan - I've determined that they are overpriced. If it was a case of ~5%, then I would not mind too much. But, it is 15% more expensive. Since these translate directly to revenue, I am very price conscious. Also, Bitmain has a lead time of 2 months, which is less than others, with 3 or more months.
If you want to hop on a phone call with me sometime this week/end, I'm throwing together a group buy and have been confirmed for the April Shipment. I don't know exactly how many they're going to give me in terms of allocation though. So far I asked for 200-300 units and through the group buy sign up I have sent out about ~170 Antminers worth of invoices in the last 3 days.
Here is my number 608-629-5398 Extension 101; email: matt@midwestminers.com; I'll give you my cell phone number too, just don't feel like posting that into an open forum yet.
