If I remember correctly, mine is a Sterilite 45 gallon bin with wheels. The handle is a little annoying, but it works. I was going to go for a larger Rubbermaid bin, but I'm glad I didn't: this one clears just perfectly in the back of my '05 Altima. Everything fits inside neatly (as long as you stack it correctly). My girlfriend made me drawstring cloth bags for all my armor, mics pieces (voice amp, gloves, sweat bands, etc), and a fleece bag for my bucket.
In the bottom are a couple Ziploc baggies with Plastic Welder, Krazy Glue, Velcro, spare bits of ABS, some soft cloths, and a couple other things.
