I have that grin!
I opted for the stealth big oil and purchased the DIY kit for $900, then found a second pump off Ebay for $225, another $100 or so in fittings so I'm in my big oil setup for$1225-ish and the DIY injectors were $960 .. But I will warn you, the DIY stuff isn't for everyone so make sure to do the research on what you're getting yourself into first!
