so noone who is building a mining network needs switches? i know their a little old but your not running a datacenter or anything for 160 bucks, less if you bought bitcoins at 14 or mined them, its a good deal.
I think nobody's biting cos they're available for 20+FS each on eBay and you're asking 170 for both. 
I'm interested, but at no more than 1-ish btc shipped for one.
