I researched getting a camper shell for my 2012 Tacoma quite extensively and, being an engineer, I was fairly stuck in state of 'analysis-paralysis' with all the brands, options, etc. I started perusing craigslist and found a Snugtop 'hi-liner', same color as my truck, about 100 mile trip away, and picked it up for $800. New it would have cost $2200+. While it was not in perfect condition (minor scratch...on the top!) and needed new gas struts ($20-ish on amazon, 5 mins fix). Turns out the shell I 'needed' was the one that was available locally. As others have suggested, start looking at your local CL ads.
