Woodstock Chimes are probably the most popular, and they're well constructed, balanced, and cleverly promoted. Some of their chimes, for example, have tubes that sound the first few notes of a classical piece. You not only get the pleasing sound of the chimes, but the pleasure of recognizing (or telling someone about) an ACTUAL musical work.
SOme may prefer the more direct aesthetic of these "bells." WIth its simple, classic design, and pleasing sounds, the chime doesn't seem to strive for something it is not. OF course, Woodstock sells these as "Temple Bells," but there's nothing inherently religious, sacred, or otherwise "Temply" about them.
That said, the Temple Bells sound is more subtle than chimes; I'd say they were more like muted bells, with little sustain. For those who want something quieter, perhaps more meditative, these may be the way to go. You can hear them, but they aren't so jangly or high-pitched become either annoying or cheap-sounding. Another excellent product, fairly priced, from Woodstock
