Lol you can still have a Bov if you choose mate inless you like the pigeon mod (no bov which stalls the compressor/makes it spin the opposite way or somthing, im tired and forget) anyhow the night pager is around 199 and come up on ebay now and then for around 100 but quiet rarely!
These do make a wikkid noise though i've only heard them on 200sx's etc
