I don't know what you do with your rig.

As these guys have said, stock ignition is good. If you just run it on the street and the occasional trail Stick with stock. If you need a new stock coil... Hell, I'll give you one!
Sounds like you are a little thin in the wallet.
Anything better then stock is going to run a couple hundred $$$.
I Love my MSD blaster 2 and 6A. I have my rig setup with a stock coil and the MSD so I can switch back and fourth by swapping the coil wires.
The difference is noticeable right away. When the engine fires on MSD, it explodes into idle. Hooked to stock, The engine just kinda starts up.
Sitting at Idle, the MSD has a deep, mean, tone, sounding precise and clean.
Very smooth and tight sounding.
The stock ignition at idle, well it stays running but I wouldn't call it very even or clean. There is no deep tone at idle and the engine sounds loose.
The MSD Fires a rapid succession of spark for 20 degrees of crankshaft rotation up until about 3000 RPM. Not to mention, with 480 volts going into the coil, the output is also higher then stock.
What this means is more of the fuel/air mixture can be burned per cylinder cycle then a stock system could ever dream of.
Taking the truck for a drive, The stock system run well, there is good power and it runs smooth through the gears. It really is a pretty good system.
But Technology has advanced.
Putting the truck in gear and letting out the clutch is a whole new ball game with the MSD. The low speed Crawling is unbelievable! Without even giving it ANY gas, the truck will idle up pretty much anything. The low end torque is REALLY Noticeable. On the road, it has more power throughout the entire powerband! I get better gas milage with the MSD and the truck just sounds so much better.
MSD is not reliable though. The first box I had was the MSD offroad. it got to the point I had to smash the MSD box from time to time just to get it to run.
That is why I run the stock as a backup. MSD is awesome, but instead of meaning "Multiple Spark Discharge", I think it really means "Might suddenly Die"
There are other aftermarket companies that produce high capacitance discharge ignitions but I have not run them.
The MSD that is in my truck now I have had for over 10 years, it has been in 4 different truck and it is still burning strong!
Let me know if you need that coil, I have a few layin around.
