I have not looked that much at cheaper controllers, but the lack of a heat sink is one obvious difference. And yes, providing a heat sink at a reasonable cost should be easy. I can’t explain why the market has not offered that.
But how about a Tri-star 45 for $161? http://www.ebay.com/itm/221681616399?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

If you believe heat sinks are reasonable take a heat sink tour of eBay, electronics suppliers and manufacturers. The price them like they are manufactured from copper. And the cheap @#$/\&!, s don't even bother to black anodize them. A heatsink for a working MOSFET is not small. I am forced to use 7 fin 50X40 mm sinks for my LED buckers. Heat sinks are the bane of the LED industry. You hear screams THIRTY WATT LED LIGHT and find out it's driven at 20 watts with a hot as hell heat sink.
Working with newer electronics and their cost structure has really given me an education about heat sinks. Devices are taxed thermally to the bitter limit and of course the fluorescent tie & paisley shirt crowd lie like hell in order to sell merchandice. Welcome to the age of B.S. There's no one out there to trim their horns.
