Spring straps do not have to be expensive. You can make your own for under $20 per pair. Cheaper if you're making multiple pairs, order the springs at the same time & save on shipping. The springs sell for $4.99 each, so $10 plus postage gets you the main component. A foot of delrin 3/4 inch rod to make the blocks with is about $5.00 plus postage. You should be able to cut 5 pairs from a foot.
There is a thread on how to make them in the Do It Yourself forum, go take a look.
