Hey guys,

As afore mentioned, I priced a reconditioned pole pig at $1045 
Australian. However, they will sell me an unconditioned unit for $500 
Australian (about $250 US). They say the only test they will do on the 
transformer is a megger test. What is a megger test? Is this a reliable 
indication of the transformers integrity? Would you guys suggest saving 
for the reconditioned unit or buying the "as is" unit? I figure I can 
buy two of the "as is" uints for the price of 1 reconditioned unit, and 
the chances of both being duds are minimal. What do you think?

Cheers,
