Ones expensive and one isn't, One you can buy parts at any store, One you can't, one you can fix on the side of the road, one you can't, One might give you better fuel milage, Both will require tuning, however on doesn't need a computer to do so... take ur pick.

Holley's need a computer to tune? This is news to me. The whole point of the ez-efi is that it doesn't need a laptop to tune so that can't be what you're referring to... 
Seriously though, unless you daily drive the car, I think you'd have a real had time justifying the cost of going to efi.

I'm talking about the on-board unit, not a lap top.

Lots of EZ info on my web site including a list of how it differs from the XFI. www.fastmanefi.comI can answer any specific questions, but I can say that most problem installations in Mopars are improper fuel system setup, and intermittent switched 12V (by this I mean the power dropping out as the key goes from run to start and back), or noisy tach signal (the EZ needs a clean tach signal like from an MSD 6AL).

Years ago, I was fooling with Holley's Projection system, the old analog Alpha N setup.
Junk, even with the optional O2 setup. However, it did teach me a valuable lesson. Your fuel system is key, especially the pickup portion of it. On the days the system ran well, I could easily kill the engine with a hard turn or stop with less than half a tank. Some one mentioned Rock Valley, good choice but pricey so factor in that cost for your budget.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Efi isn't something you do because its cheap...You also don't do it, because you wanted simple and no wires showing.
The EZ-efi is about as simple as it gets, but the fuel system needed to support efi will take a little thinking or guidance to get it right the first time.
I like my EZ efi, and I can say I hit a few bugs or issues along the way. Most are attributed to +30yr old Chrysler wiring that was never meant to work with more than an amp or two thru it...And one fricken PITA intermittent coil failure I could not locate...But finally found.
It is very responsive almost instantly. It is very, very tuneable on the fly with no tools, or laptop. And it will keep the tune right on the edge regardless of outside temp, humidity, or altitude...No carb will do that...Mine also netted almost the same ET back to back...It will as noted run with a bunch of sensors not hooked up or functioning...Really great in that respect.
A good running carb is great, EFI is awesome.....

i am no fuel system expert by any means but have you looked into msd's atomic efi? from what i have seen it looks relatively easy to install.
EZ has a return style system, keeps the fuel moving. MSD is a dead head system. Both systems are relative in nature other than that. MSD has the brain built into the throttle body. EZ is separate.

I also ran a Holley Projection. Non standard parts and a rotten analog ecu killed it for me. However, part throttle response absolutely blew the carb out of the water. I always thought that TBI with a good ECU would work fine for most of our cars. We will see I guess.

I have heard of some guys running that ecu with one of the generic aftermarket efi controllers and having good success.

one you can buy for a couple hundred bux the other will cost you more than two grand by the time your done.
