That's exactly what I just did. 5100's were about $360 shipped. You can save quite a bit on the Daystar spacers if you purchase them from Amazon as a FJ Cruiser spacer. They are different part numbers but work fine. I paid ~$35 for mine.
I don't understand why they would ever post this picture. its IS scary looking probably to most.
I think they're banking on the idea that "any press is good press". But yes, scary looking nest of wires!
