I can recommend the Aspire Pegasus. It's a 70 watt that is built like a tank and pretty reasonable on price. It takes a single 18650 rechargeable battery. I'm digging mine. Battery will last me most of the day, I'll usually swap it out late in the evening and put the one I've been using in the charger. I vape at about 28 or 29 watts.
Here's a strangely entertaining video review on it.
You can get the kit on Amazon for $75 which gets you everything you need except a battery or two and a charger, though you can charge it in the mod if you want.
