Deck screw dilemma – which driver should I get?

Hey y'all, I'm about to build a 12x16 deck on my own (first big project!) and I need to sink about 2000 screws. I've been using a cordless drill with a clutch, but my wrist is killing me after just a few hundred. What driver do you recommend? I've seen the impact drivers but I've also heard about those compact screw guns with auto-feed. I'm on a budget, but I want something that won't quit halfway through. Any advice?

Congrats on the deck! For a job that big, get yourself an impact driver, hands down. I've been framing for 30 years and an impact driver is night and day compared to a drill. They've got way more torque and they don't kick back like a drill does. You'll thank me when your wrist isn't screaming. Don't bother with the auto-feed screw guns unless you're doing production work – they jam and the collated screws cost more. Just grab a good 20V impact and a box of quality deck screws (I like GRK's). Make sure you get the right driver bit – star drive is the way to go.

I second what Wendy said. Impact driver is the way to go. I've used all brands, and honestly, any major brand will do. But if you're on a budget, look for a bare tool if you already have batteries, or a kit with two batteries – that'll save you in the long run. Also, don't forget to predrill if you're using hardwoods or near the edge – expansion can crack the wood. And a tip: drive screws slightly below the surface but not too deep, especially if you're planning to sand and stain.

All good advice. I just want to add: if you're going to be screwing overhead or into tight spaces, an impact driver is lighter and more compact than most drills. Also, get one with a belt clip – you'll want it handy. I've used my Makita compact impact for years, it's been through rain and mud and still works like new. But I also want to throw out there: have you considered a corded screw gun? They're cheap and they've got a depth control that stops the screw at the same depth every time – that can be a real time-saver if you have a ton of screws. But you'll need a generator or extension cord, so probably not ideal for a deck. Stick with an impact.

Thanks all for the quick replies! I think I'm sold on an impact driver. I'll go with a 20V set from a brand that has batteries interchangeable with my drill – good point about the bare tool. I'll skip the auto-feed since you all warned about jams. One more question: should I get a square drive bit or a star? I saw both and wasn't sure which is better for deck screws.
