You might consider investing in a set of bells. They can come in handy in a variety of musical situations--- choir anthems, cantatas, hymns, and worship songs.
Glockenspiels come in two flavors: Steel and Aluminum
Steel: Best sound, Heavy, Pricey
Aluminum: Sounds okay until you hear steel, Lightweight, Easier on the budget
Some bands use the bells from beginner percussion kits. It works. Mike 'em up and throw on some reverb. You can get the desired effect.
My "gig glock" has aluminum bars mounted in a case which reflects the sound (like a resonator).
Check out the song, "When I'm With You" from the Great Great God CD from Gateway Worship. About three minutes into the song, many instruments (guitars, bass, keys) play a melody in octaves. After a couple of statements of that melody, I bring in the glockenspiel to give the passage that sparkling punch that the bells can deliver.
