here is some free and unsolicited advice. agree/disagree?

situations you will want a cordless drill:

• you are working where there is not guaranteed convenient electricity available
• you need to be extremely mobile and a cord would be hazardous or very inconvenient
• wet environments? idk

examples: rough construction, outdoors, drywall racing

benefits of a corded drill:

• no batteries to charge
• no batteries that can be stolen
• no batteries you can lose or break
• no need to plan around charging batteries
• no batteries which allow the manufacturer to twist your arm into buying a new device when the old one works just fine; less susceptible to planned obsolescence
• no batteries to weigh the tool down: lighter and more comfortable to use the tool and better balance
• tool is smaller and easier to use in cramped situations
• don't need a case, charger, extra batteries or other junk
• one less thing to go wrong; more repairable if it does
• more powerful

you are in a comm called "DIY" = you are probably always working near a power outlet and not going very far. consider a corded drill instead of mindlessly going cordless.

Make sure you get a decent extension cord. I used heatshink tubing to add an extra 6ft to my cord, that makes it long enough for many applications. Sometimes I tie on an extra one.
