Beginner-friendly, affordable espresso machine: I decided to try a home espresso machine after using my aunt's $999.95 Breville Barista Touch when I visited her in Texas several months ago.

Q. I love the sound of my open-back Grado headphones, but in my old age (55) I am over the constantly twisted cables and overall discomfort.

I thought about upgrading to one of the other projectors you have written about, but some of them don't have built-in Netflix either. What do you recommend for around $1,000? ...Read more

Extremely versatile, super-powerful mini blower/duster: When I first saw the Wolfbox MF50 Electric Air Duster on Amazon I thought it would be useful for removing dust from turntable styluses, but it turns out it can do so much more.
