Anyone have experience with 12v power supply for the SBIG ST7?

I'd like to use mine on my portable setup out in the field, running from 12v. The SBIG 12v power supply is pretty expensive - something like AU$280 I'm guessing, by the time I get it.

Another alternative I'm aware of is buying an inverter ($59 for a cheap one, $230 for a better quality one, both 150w).

Any other options that are more affordable than $280? Surely the power supply SBIG sell must be available elsewhere cheaper, or something similar?

Thanks for any info,
Roger.
