I put this system on my 545 after considering many of the EFI setups available. I had the standard big Holley previously and wanted to preserve the conventional look somewhat rather than a stack setup. I talked to Chris at Mass-Flo a number of times and finally went ahead. It was worth the money to me, I like it, and it solved all the concerns I have always had with my carb setups. I spent extra for the fuel system kit, probably if I did this again I would source my own parts especially a smaller inline fuel pump which I have since changed to. Chris shipped my system, injectors, computer and everything based on my CID, cam, compression ratio etc. It starts right up cold or hot, very smooth accel, so yes, for me it was worth it.
