Truck: 1997 Powerstroke 7.3l diesel.

I'm having trouble deciding between these two kits: Golden Fuel Systems WVO kit & the BioFuels Technologies Vegistroke WVO kit.
The Golden Fuel Systems kit costs $3,379.84 and comes with a heated tank.
The BioFuels Technologies Vegistroke kit costs $3,495 without their $825-$1,225 heated tank.
The forum posts about the BioFuels Technologies Vegistroke kit also mention that my year model truck has to be converted to electronic fuel injection to work with this kit which also will make the BioFuels Technologies Vegistroke kit more costly, where as the Golden Fuel Systems kit doesn't require conversion.

Can someone with experience with either or both of these kits say whether the BioFuels Technologies Vegistroke kit is worth $1000+ more than the Golden Fuel Systems kit?

Thanks in advance

 

make YOUR own its a lot cheaper lot of guys end up selling their kits because more resturants are selling it directly to vendors
