I'd say Fujita or Simota for our cars, they are probably the 2 best designs for the 3. The first gen Fujita's were a bit troublesome but have since been redesigned, and I love mine. If you get a Fujita be sure the part number is CA2504, I forgot what the first gen ones part number was, but that is the one you want. Also, E-bay is good if you know what you are looking for and you can "trust" the seller, however I wouldn't recommend buying off of there because some people false advertise parts, i.e.: The AEM's have a MTX tranny design and an ATX tranny design you will need to get the right one to fit your car, trust me I bought the wrong one, and it was not a good way to blow about $200. That being said go for the Fujita F5, you'll love it.
