Tell me why I should or should not switch to fuel injection!!!!!!!!!!!!!!

First off, my cars only have one carb each. You can't compare the price of 3 carbs for 3 cars to one car with FI. Second, quantify "Big". I have a 650, a 750, and a 600.
Second, I have yet to have to tear my engine down due to a cam LSA not being compatible with my carb. Last, to repeat, it depends on if the op is more of a mechanic, than an electronics person. I never said anything against FI, except to point out that alot of others have had issues. For me, it's not worth the expense, time, and I don't use the cars enough to justify it.
