Injectors - aftermarket vs remanufactured vs service

[T3rminator]

Just seeing what people's experiences are with the various options on injectors. In the process of ironing out an annoying issue, and with the car now close to 300,000kms, I think the injectors deserve a look. OEM injectors are no longer available. So options are:

1. Aftermarket injectors - ICON series (PAT) seems to be most readily available. Anyone had experiences with these?

2. OEM Remanufactured (not refurbished) - Seen a couple of shops selling remanufactured Bosch injectors. Cheaper than new aftermarkets. Is this a good idea?

3. Get the current ones serviced - cheapest option, but will it do the same job as a remanufactured? Have heard that if it is leaking, and depending on cause, it may not be servicable and I'd still have to get a replacement. And what kind of $$$ are we looking at for a good service, I've been quoted anywhere from $30 to $70 an injector. Big differences there.
