Fuel injector question

I have a 91 5.8 engine in my 86 F150. The injectors are from the original 86 5.0 engine and I have over 300k on the truck and these injectors. I've got at least 1 leaking pretty good and flooding what feels like 1 cylinder as I sit idling. I've been looking for some new injectors and would like some feedback on what to use. I see some Bosch 4 hole for 50 buks per set yet others for as much as $350/set. Any advice on whether the cheapies are OK or do I need to spend a little more?

I bought cheap rebuilt injectors on eBay for my 460 and have had no problems. That was about 5 years and 60K miles ago.

I bought these for my 94 with a 302. They work great and installed just like the stock ones.

Several of my injectors leaked, causing my engine to stumble when the throttle was opened quickly. For $25 per injector, a local place tested and reconditioned each injector. One injector measured low impedence so I had to replace it with a new one, but the other 5 were able to be reconditioned. Afterwards, the stumble was gone.
