I too would suggest a DIY. You can get some bulk Carol cable 12/3 at Home Depot and pick up some Hubbell ends at your local electrical supply house. I would also suggest getting a circuit tester & IEC to AC adapter.
The adapter is called IEC C14 to NEMA 5-15R - 250 Volts and is about $3.00. The tester can be purchased at Home Depot for $4.00 & is a GB Electrical Model HCA300.
