I have a small Tilia "Foodsaver" vacuum sealer that they used to have at Wally World for about $35. I believe it's called the "Mini". Might be too small for what you're looking to seal, but they also make bigger ones.

It sounds like this is a kit you will keep sealed up and don't want the contents pilfered. Vacuum sealing is a great idea for that.

My day to day stuff in my BoB I just keep in the handy ol' Ziploc baggies, in case I need access. The trunk kit has most items vacuum sealed.

Plus, it's fun to seal stuff up! <img src="/images/graemlins/cool.gif" alt="" />
