I don't know if it's just me, but this page isn't loading:
Do you have Javascript disabled, by chance? JS and Flash are required to display the product configurator.
I did some looking around, and I can't find another way that you might have arrived at this link (unless perhaps the JS did not initialize correctly).
If you still have trouble after ensuring that JS and Flash are both available, drop me an e-mail at scott@weareinstrument.com and we'll look into it right away.
Thanks!
