Hi guys, I was helping my dad with some general DIY stuff around his house the other day and he mentioned that his drills had all crapped out. Needless to say, we had to use screw drivers for everything, which took forever, especially when we were screwing heavy things into the ceiling... I've been doing a lot of research and I want to get him some new tools. He is a general contractor and knows his way around tools, but I'd imagine the drill will be used mostly for DIY stuff around the house, as he has crews that do all his work for him at jobs now. He's more of a manager now than anything, as he's getting older and can't really handle the stress his body gets put under in the field. Every once and a while he'll do small jobs, when it doesn't make sense to send a crew out to do it, but nothing that'd I'd imagine requires heavy work. That being said, I want to buy him something that's going to last. I believe the problem with his old units are actually just the batteries, but the cost to replace said batteries would be more than just buying a new drill in most cases. Budget would be $150 or under. I'd imagine it'd mostly it'll be used for wood work, screwing into drywall and maybe some metal sheeting. There HAVE been times when he's had to drill into concrete, so if there's any drill/impact drive combos out there even worth looking at in my price range, that might be cool, too. Really, I'm looking for something that has a long battery life, is reliable and has a good warranty if something goes wrong. Ryobi seems to have some really great deals on what you're getting, but from past job experience on my part, they can be iffy in the reliability department (though, I haven't used any of their newer stuff). Bosch and Ridgid are really what I've been looking at, specifically, these: http://www.homedepot.com/p/RIDGID-18-Volt-Hyper-Lithium-Ion-Drill-and-Impact-Driver-Combo-Kit-2-Tool-R96862N/203070347#.UbdDTvZ4beM http://www.ebay.com/itm/Bosch-DDS181-102L-New-1-2-Driver-Drill-Kit-BAT612-2-0-Ah-L-Boxx-2-Warranty-/161041585989?pt=Drills&hash=item257ed39745#shId It's a little over budget on the Ridgid, but I'm also getting 2 tools and a Lifetime Warranty, which definitely makes me feel better about it than Ryobi, DeWalt, etc. However, I hear iffy comments about whether the Ridgid batteries can last a good amount of time or not? What else would you guys suggest?
