Sorry to be out of touch since last night but the computer was at fault. I missed having my morning coffee while checking NGA.
I've used cheap, as well as expensive trellises, so I'd say anything that's strong, preferably metal, would be fine. Look at Home Depot but they may not have any/many in stock in fall. Our Lowe's always had a good supply of varying sizes. You can look online - places like Pinterest may have some you could try and find.
