i just wished id bought 100 of them one a few yrs ago when they were £35!
ebay ones were selling for approx £50 plus delivery when i looked. probably better getting one from the forums.
hahaha your'll be lucky to get one on ebay for under 70! last two i saw went for about that price.
keep checking on forums, when people sell their cars and return to standard, its often the first thing to go as its easy to install etc..
