Rebuilt fuel injectors

Gentlemen
i have a 1998 Lexus GS300, its been to 2 shops and they cant fix the stall in the acceleration, they have changed all the electrical parts and even the fuel pressure regulator, what it does is when you press on the gas pedal for a quick take-off it stutters for about 6-7 seconds then clears itself, if you slowly press on the gas to accelerate slowly then there's no stutter , i am down to replacing the fuel injectors and i wanted to know from everyone,
**ARE REBUILT INJECTORS A GOOD CHOICE VICE NEW ONES**

my garage wants to put new ones in but the guy wants $145 dollars per injector--OUCH!!

i think he,s ripping me off and i want to know from the forum whats should i do
please advise

I'd go with new injectors, but rebuilt are good if you trust the rebuilder.

Here's new OEM injectors for $80-83 per injector:
