Hey guys,

I want to join the Bitcoin mining horde and what hardware I am thinking about buying is this Butterfly Labs' 600 GH/s card http://www.butterflylabs.com/monarch/

Is it a good investment right now? Is this site calculator any accurate http://bitcoinwisdom.com/bitcoin/calculator ? It shows I can get back my money (new price of the card is $2196 instead of $4680 as shown on that website) in less than 20 days if I start now. If all the numbers are true or close to what I will get, it is darn good investment for a Bitcoin newbie like me.

Thank you all for your inputs.

The key words of above statement are "if I start now".
You will not start now. That I can promise you.
BFL does not have a very good record of keeping their delivery promise.

Chances are very good that until you will receive it the difficulty is that high that it will never ROI.

My advice: Stay away from pre-orders.
Only buy what is in stock and delivered to your door within 3-4 days.

Thank you torusJKL for a very helpful post. I was a bit worried about delivery date too after reading my posts here about pre-order nightmare so I emailed them asking their delivery date and no response yet.

For other choices in hardware, what do you recommend? I prefer add-in card like the Monarch because it's easier to have someone in US order 1 for me and ship to me in Vietnam.
