Assuming you don't have a percussion specialist on staff, you should use this chance to examine and upgrade your accessory percussion and hardware.
For $1000, you can get a couple new concert snare stands, a new triangle with good beaters, a new pair of chime hammers, a new high-quality tambourine, a set of concert toms with stands (or new heads if you have a set already), put new heads on your concert bass drum, and then replace the slightly less commonly used stuff. Get a guiro that isn't cracked (if yours is). Buy castanets. Buy a set of good quality wind chimes. Buy a pair of finger cymbals. Get all of the little things you may have had to substitute for in the past 4-5 years so that you have what it actually calls for.
Get a new "school set" of timpani mallets - very soft cartwheel to very hard, since your kids will likely only have a set of general mallets. Buy a large enough bag to hold them.
If you don't need most of that, look into a really good suspended cymbal and/or pair of concert crash cymbals, but that will eat up most of that $1000.
Seriously. All of these seemingly unimportant "little things" make a WORLD of difference in how your band sounds. Spend the money for quality and show that you value the bottom of the percussion section as much as you do the top.
