D90 Intervalometer Options

[sundog]

I'm looking for a D90 accessory to allow time-lapse photography. Currently, there's no built-in intervalometer function nor an equivalent MC-36 remote unit available from Nikon.

These are the only 3rd party units I've found so far:

• 
  Satecki TR-M Remote Timer Control (which seems to be unavailable)

• Satecki LCD Timer Vertical Battery Grip (limited to 99 exposures)

• Opteka D90 Timer Remote Control

Has anyone had experience with any off these or know of alternatives? The Opteka remote looks especially attractive at this point. It's limited to 399 shots; however, I read somewhere that you can set it to a manual setting, which then runs until you stop it.

On ebay you'll find others like Jianisi & Yongnuo available direct from Hong Kong ( or similar locations ) in addition to the ones you've already found either under different names or anonymous.

e.g. http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=d90+timer&_sacat=See-All-Categories

No experience of them though.
