Consumer-level Lambda exhaust probe?

[crofty1984]

Hi All,
I'm talking about use on classic carbed cars and bikes, I don't want a permanent welded in wideband O2 sensor and dash display. But for tuning purposes, is there something similar to the kind of exhaust probe you see during an MOT or dyno run you can by for a reasonable amount of money?
