Yes...stay away from ebay chips. Those are nothing but crap. Chipping for hondas in our experience...and from our client's as well...has proven to be very very effective when done CORRECTLY. Most chips like skunk2, mugen, spoon, etc...are plug, play, and pray (that they run your car correctly).
VAFCs, piggybacks, and other little boxes that trick signals going into the ECU have their drawbacks too. Personally I'd go for a well tuned chip than hook up a VAFC in my car. Yes these still give you HP when tuned correctly, but tricking the ECU will have negative effects. The ECU is a pretty smart piece.
