With respect, as someone relatively new to the game..... may I offer the following insights and comments:

• The timing and structure of this sale prevents a newcomer to the BTC economy such as myself from gaining access - I needed to sell stocks, settle the trade, transfer money to a bank account, wire money to Mt Gox and then finally get BTC to fund a purchase of Avalon equipment. Total delay estimated at 8 - 10 business days - not your problem I know, but worth mentioning perhaps
• Despite issues of timing, if I take the $16,000 investment for 2 x 85 Gh/s (ttl 170 Gh/s) from Avalon and (ahem) pre-order BFL machines now for an estimated total of 720 Gh/s purchase AND allow for in excess of doubling of difficulty from 12,000,000 to 25,000,000 for delayed delivery I show a total return of $125,000 for Avalon and $273,000 for BFL respectively based on a time frame of 12 months
• NB- I have a window of recourse with my credit card company and perhaps paypal should BFL not show sufficient evidence within the next 30 days that they will deliver product - no such opportunity or recourse exists with Avalon
  

Clearly, I have opted to order from your competitor.

Should your value proposition and business model shift to a more competitive stance in the future I look forward to having the option to become an Avalon customer as well.

Best of luck with Batch #3 and beyond and thank you for your groundbreaking contribution to the future of Bitcoin for all.
