remote shutter release for D90?

[Lukeeee1990]

After the above however I do have a cheapy one that works fine but won't work when in bulb mode; do I need a wired trigger for this? if so does anyone know where I could get one that would let me use my D90 in bulb mode without use the shutter release button the camera itself?

thanks

I bought an el-cheapo from LinkDelight on eBay and it works in bulb mode - first press opens the shutter, second press closes it again.
