Power supply conversion

I bought 10 AT style computer power supplies.  I have 
converted two into a modeling power supply that provides 
both 5 and 12 volts.  They run my charger and 
receivers/servos, but not my foam cutting hot wire.  I want 
to sell the remaining 8, along with directions.  The final 
cost to do a conversion would be about $40, including 
****pping and parts.  Is anyone in this group interested, or 
should I put them on ebay?
