I think the one Tracy sells is as good and inexpensive as they come.  All of the ones that I am familiar with use the same basic design (except for the latest ones that use the new (and expensive) so-called broad band sensor).  I personally like the ones that use the 3/4 wire sensor (these have their own heating element) as you do not have to wait for the exhaust gas to warm up the sensor before it start working.  They are a bit more expensive that the 1/2 wire sensor may $10-20 more.
 
I built my own LED A/F indicator  and integrated it with my fuel monitoring system.  But regardless of whether you build or buy, they are well worth having, in fact I would rather lose my EGTs than my LED A/F indicator.

Thanks Ed,
By any chance can you recommend one A/F indicator?. I have installed the single wire O2 sensor that came with the engine. I may even replace it?
