just remember the simple line of "you get what you pay for..."
in my experience i've heard of the following
honda accord exhast mani cracked, looked nice, but cracked in 4 months, and obx didn't want to warranty it
honda crx short shift kit- broke right in half (right at where it sits in the body) a year later
honda civic rear lower tie bar, came short of pieces and the thing started rusting out in a few weeks worth of driving (this was in the winter, i know i know, salt and water exposure blah blah, but i've had no name brands on my acura that never rusted out like that AT ALL)
i would search the board and go with a trusted name that everyone is accostumed to, you spend a little more now, but you'll be happy with it in the long run...
1995 325i- slushbox, cause i like it that way...
Soon2B- ??? - manual/stick cause i like it that way ?
