Get it direct from Alpine. Even though it is not supported by TRD or Toyota any more, Alpine still sells them, and will get you a quote if you email them. Google Alpine Supercharger to find their website.
Alpine can sell it to you with or without the Uni-Chip. Most people on CT would probably recommend you to ditch the Uni-Chip and go with a URD for the ability to do end user tuning. I forgot if LCE's kit includes the Uni-Chip or not.
