I would be okay with 2btc for 600mHash. but for 300 i dont see it as a ood investment
Most people don't. I didn't when I purchased one via a group buy. I had other motives.
Most likely everyone who owns one of these things at $200-ish US is going to feel like they were gypped to some extent every time the look at the thing. Further, most of the people buying them now will probably be especially active in the mining gear economy going forward.
Due to the rapidly changing events in asic-chip-land, it's possible that ~friedcat would make a decision to do some two-for-the-price-of-one deal or some such which would be much less messy if done before any items were shipped at all.
I anticipate once the first batch ships, and we see other competition catching up on pre-orders or avalon-based designs, we could see a more reasonable price/power ratio.
I would not purchase any asic design unless i believed it could pay for itself within 6 months, especially since 60% of that would probably occur in the first 3 months. For me, I want to see 4 chips on a device, with a total of >1GHash for less than 4.5 BTC after shipping/taxes/etc and a few reviews before i invest in such a crapshoot.
There will be a period of time where early investors profit (that was avalon batch 1 and batch 2), then a period where the asic technology will advance and drop in price at a rate that makes investing in the earlt part of the phase a poor choice (IMO, this is avalon batch 3 and the block erupter v1). Eventually this will level out somewhat, probably in a few months, and the ideal opportunities will arise with 16-chip designs that push 6Ghash a board in the $750-$1000 price range. Every year this price will half.
