If your looking for a very inexpensive box call that sounds good for only about $25
On eBay regularly there are box calls offered up by Daryll Helm
I have bought a couple for around $20 plus $5 shipping. The last one I bought was spalted sycamore with a cherry lid and ebony inlays,,and it was a nice little call with a pretty good medium to young hen sound and not bad to look at. No these are not on the level of quality like the $100 plus ones like SS or Harwell,Paul etc. But for $25 they are much better quality then a store bought over the counter one, I won't hesitate to take mine if it looks like a messy day and I don't want to bring my pricy boxes out in the elements.
Try one on eBay their a nice value.
