Sorry no matter how expensive your electricity is, you are paying $980 for 700Kh of LTC mining when you can get that for half the price in a GPU.
At 500 watts for a single GPU giving you 700Kh you would pay $54 a year (at $0.15 Kwh) to run it.
The breakeven on the electricity would require you to mine for 7-9 years before these devices recovered their excessive cost.
For easy math, a GPU of about 700Kh mining costs $500 (for round numbers) so for these to be competitive they have to cost $50 USD
When they hit that price (or close to it) you should buy all you can get. There is a small window then Alpha T starts selling their units.
