Going through the tech talk section here, I notice a dearth of requests for requests about the a/n brands of boomboxes. I've always found Sanyo to be real workhorses, sturdy and reliable. I've never seen a National, but I've been told they're the same things. ARE these makes what I have found them to be, or have others just found them to be PITAs, and chucked them rather than repair them? I snagged a Sanyo MCD-Z41 at the Sally Ann for 10 bucks CDN t'other day, and I'm well pleased with it. It's not the loudest, but the sound is great, and the BassXpander does what it's supposed to.
