This is more of a home owner question than bike question, but the arrival of a bunch of bike specific tools lately (just did my first bearing overhaul) and a general clutter of tools from DIY projects around the house, plus a desire to have all the tools in one place instead of 83 different "kits" has me wondering if there's a plastic or cheaper alternative the the big rolling metal toolboxes.

Thought someone here might have some good suggestions.
Thanks in advance for your time and advice.
