Have just sold the wife and kids on ebay, raised a cool $1600 (less handling and postage) - it's all going NEN.
Figure I might buy them back latter (less depreciation), after the second drill, for around $1000'ish.
It'll be all clear profit - less offsetting adjustments for CGT/depreciation of course.
Might try it again later with STX - call it a roll-over facility.
