I recommend ebay seller alienbid’s “New 9 Folding Multiple Guitar Bass Holder Rack Display Stand Black” if you need an affordable guitar rack.
It’s about $19.79+tax, including free delivery.
The rack is well-made from steel, and is strong. It feels like a precision instrument as you thread the bolts into place. No tools are needed, as the bolts are thumb screws.
No extra parts are included. There is a half-page assembly guide but it’s not that helpful. I recommend having somebody help with holding parts during assembly. That way you will save a lot of time and avoid stripping any bolts.
I’d prefer if the neck dividers were cupped instead of pegs. Currently I use padded mailing envelopes to ensure there’s no “stand rash” in case a guitar twists sideways and touches the next one.
I stripped one “bracket screw” during assembly, so I sent an ebay message to the seller. He replied the next business day (in the morning), and I received a complete set of bracket screws in a bag via USPS five calendar days later for no charge. I consider that excellent customer support.
I have no idea how they can make or ship this for $20. I should get a second one.
