Don't panic, I can solve all your problems. I assume it's not a switching power supply cos if so you can just buy a plug adapter.
Assuming it's not go to jaycar and buy this (check the wattage but this is what mine took):
250W 240 - 115V Isolated Stepdown Transformer | AC-AC Transformers | Power Conversion & Transformation | Power Products Electrical | PRODUCTS | MF1082 | Jaycar Electronics New Zealand
The price won't make you happy but it's cheaper than a new tumbler.
You don't have to wait for media. The cases will get clean (except the inside and primer pockets) if you just tumble them. Use hot water, a few drops of dishwash and some citric acid (supermarket).
For the media collect up $100 worth of stuff on cabelas and put in an order. Select ground shipping and it will cost you $125usd and they just send it air anyway. Arrives in a week.
I could use another packet of media if you want someone to share costs.
One of these is very handy, they also have a seperater tray thingie.
