hey everyone...

well im considering installing a carputer so i can run my logging and tuning programs without having to set my laptop on the floor or passenger seat. i noticed on the mp3car online store some pre-packaged carputers and was wondering if one of those would be worth the money or should i buy all the parts seperately? i am kind of on a tight budget for the moment so whatever will get the job done (logging/tuning/music without a lot of extra stuff added in) however i would like to add navigation to it at some point.

im looking at this one right now:
Carputer

any input would be great, thanks
