I'm a Leviton shop, but in my residence I'll use any brand name or any off-brand and never worry about insertions and contact material. Names like AMP, Hubbel, ICC, Leviton, Gruber, Avaya/Systemax/Whatever, Panduit, and the like can compete for my attention and they're all good. A quick Ebay search of 5e patch panel brings 38 panels ranging in price from .50 to 5.00 a jack. I'd buy any and all items listed for residential and at least half of them for commercial accounts.
Or I'd pick up the phone and call my distributor and order an ICC or Leviton or whatever the customer specified panel.
