Say, those transformer like things, are those your 150µH coils? According to the datasheet they should look quite different... http://www.vishay.com/docs/34022/ihv.pdf
I'm actually using a separate power supply for LCD monitors. I got it on ebay pretty cheap:
AC Adapter Power Supply for LCD monitor TV+Cord 12V 5A - eBay (item 260377413127 end time Jun-12-09 12:29:57 PDT)

I like it because it'll work on 120V or 240V and up to 5A (not that I'm anywhere near 5A). it's gotta be some sort of SMPS, maybe a flyback transformer? I haven't taken it apart.

The inductors are the two square-ish looking things with the copper coil in the middle. See the link to coilws.com in an above post... The big black transformer in the background on the table is a multitap transformer I set up as an isolation transformer so I could still use the scope.

Why are you getting such high amp rated inductors? Something smaller might suffice? Of course, over-designing might help you be successful the first time!
