I have been using a Plano case for the last 7-8 years. No complaints, still works great. I did glue some additional foam padding in to it, and use foam pipe insulation over the limbs. Probably overkill, but I’ve had zero problems and my bows have always held zero.
I guess I do wish it had a storage compartment for small tools, broad heads and other small accessories. But I have a small case that fits in the space behind the buttstock that handles all of the small stuff.
I think the case was around $70-80
