Hi Mark,

    I've rented equipment like this when I didn't want to spend the 
money on something I wouldn't use for long.  I've used one like this on 
ebay (for $2250) that can generate 0-270VAC and something like 30 to 
120Hz from a straight 120VAC 60Hz input.  There's also one with a serial 
port, but I never used it - anyway I'm always wishing I had one for my 
own business :
