Those ASICMiner devices have always been overpriced. ASICMiner and Avalon units consume way too much power. Those BFL Singles are decent devices. Those AntMiners look very promising. KNC or BitFury are amazing devices. I dare you to ask anyone who has any of those and see if they're losing money.
My V1 Blades have paid for themselves a few time over - they've been totally solid and reliable, and just hash away in the corner with zero intervention. Same with the Jalapenos.
What
is annoying is the ASICMiner Cube - it's unstable at best, uses quite a bit of power. I'm not sure it'll ever pay for itself, but this winter it's keeping the living room about 2C warmer than usual this time of the year, and all summer it'll cost nothing to run thanks to free power.
