research "tech edge" I bought this unit, its the best bang for the buck. I bought the top of the line unit, with optional in car gauge, it works mint. It is very resonably priced, and it does datalogging, and you can add the optional gauge to watch while driving. The gauge is a pretty basic ugly looking thing, but the unit works great. You can datalog with your air fuel ratio and I believe up to 2 additional inputs....such as rpm, speed, tp signal, maf, etc.
WB2BO was the unit I purchased.

The prices are in AU, but canadian was somewhere around $600CAN for the kit I believe, plus the cost of the sensor(I used a bosch lsu4 from an audi TT, cost about 80 can from queensway volkswagon)
so far has worked well with the guage, and I am just starting to experiment with the datalogging.
The great thing about this company is the tech support, and the software they offer, they made it fully upgradeable, and develop new software regularly. They are even developing software for datalogging with a palm pilot, and there is future software being developed to use a gameboy advance for datalogging and display purposes. And all the software they offer is for free!!!
