I just struggled a bit with this very issue, and here's what I ended up doing. I started with a couple used Mole Richardson 1K fresnels. I got each for about $150 off eBay, used in good condition. Beautiful lights, very robust, and easy to control. They're my bread and butter--I use them on everything. Next, I hopped over to Home Depot and picked up some dirt cheap clamp lights. Fitted with some high-wattage incandecent bulbs, they're great for accents, hairlights, background splashes, etc
