You can get a magnetic net release without the bungie cord for 10 bucks. I bought one and added my own cord later using about 30 or 40 cents of bungie material I bought at a rock climbing store, a copper crimp you can get from the electrical section of the hardware store (you'd have to buy a box and need a crimping/wirestripping tool), and a lobster clasp off a cheap dog collar (about 60 cents) I bought at a surplus store. It might be difficult to find the same stuff and is probably not be worth it if you don't already have the crimping tool, but it cost me less than $12 bucks all together.
