last year the saint louis chamber chorus acquired a lightly used set of eight Wenger tourmasters (meets your requirements) from a gentleman who brokers sales of this equipment among musicians and sports venues. his name is Tom, and his email is <nationwidebowlingtour(a)gmail.com>

he was very helpful, and his prices were most reasonable. we had a problem with the first consignment (our fault - we gave the wrong specifications), and Tom immediately took back those risers, and then found what we actually needed. no penalties or fees, just the desire to please the customer, which he did, and as a result i am happy to recommend him to others.

I have used Wenger for years in public school music programs in my school district, but not the Signature series.  This year I purchased railings for my school.  Wenger risers are the best I have used. They are simple to set up and are durable.  

 

Here is Wenger's video on these risers.
