Indeed. It's just that every time I look on eBay I can only find pre-assembled modules for DC-to-DC applications (rather than AC to DC). Maybe one of the guys messing around with DIY circuit board design could be coaxed into designing such a module. I really like the no-soldering, screw-terminal convenience. And the eBay/Asia price is less than you'd pay for shipping from DigiKey!
