The Babies

I've played were pretty much inaudible unamplified. There
is the Acoustic Baby Bass available, which may be slightly audible; I haven't played that one.
Buying a bass sight unseen has been discussed at length here, and most people warn against it. However, I own an Azola Bugbass, and I can vouch for its quality. It's a very nicely made bass. Product support from the Azolas is exemplary.
A quick look at the list prices on the Azola website shows the Baby Basses starting at $3295. That gets you into a pretty good level of double bass class; good laminates and even some hybrids can be found in that price range. I'm not telling you to buy a double bass instead, if you really want an EUB. But the money may not be as much of an issue as you think.
Bob Gollihur's website has listings for bass-related business in pretty much any geographic area, so you should be able to find out what's available in Illinois. Good luck!
PS....while you're at Bob's website, check out the the carved Bulgarian basses he sells (okay, maybe I
am trying to steer you towards the real thing

)
