Good luck with sale. I guess if you're a believer that BTC will be $1000+ each some day, 0.5 BTC each might be a good deal.
I'm a believer in what things are worth here and now. BTC could do a lot of things. It could be worthless some day too, it's very hard to say. Saying "I'll pay .5 btc now for something that costs $300 usd or 2.5 BTC now, because I think BTC is going to be worth 1k ea some day" has got to be the most ridiculous thing I've ever heard someone try to use to buy something cheaply
What I do know is that this hardware can be re-purposed, making it better than ASIC in some respects. You can mine Bitcoin now and when you don't want to anymore you can re-purpose it for something else or just sell the hardware off as it will still have a solid hardware value unlike ASIC devices.
