If you think those low buck kits are a good solution, have at it. I've taken one apart and the construction, crimping and attention to detail are not very good. I can buy those same kits in bulk for under $3 per unit. I'll continue to build a superior product out of my garage.
The engineering and system redundancy is lacking as well.
My stuff is Ferrari compared to a Yugo with those kits. It's the Wal-Mart of wiring.
