I'm sure that the LM-1 is a great tool but isn't it a bit of overkill for everyone except 'the-most-serious-tuner'? I purchased a Westach Air-Fuel monitor a couple of years back and have never had any regrets nor experienced any longings for additional features. Sure it is a narrow-band meter but has certainly served its purpose extremely well. Plus it was around $60, which is considerably cheaper than the LM-1 and the K&N although you will still need the sensor and bung.
