HELP Choosing Trigger For 645D

I have the 645D and want to shoot night shots on a tripod and Have No Camera shake. I know there is a wireless trigger and a Push trigger. I want to have the mirror go up and Shutter release. I will be using AF and NOT manual focus. Can you tell me Pro and Cons aside from the price. Thank you
Then I wish to buy one

wireless trigger cons include: so small, gets lost easy. Camera must see the beam to work, limits angle of use.

I use a cheapish $30 Chinese made programmable intervalometer which does the job well. When triggering manually, push once to raise mirror and second time to open shutter. slider to lock in open position.

I have had an SMDV RFN3 for my Canon for many years and it works fine, of course I got the same kind for the 645. Vello makes a similar thing called FreeWave, but it seems to be more expensive.

Good info - where can I get one, and specifically what is the model info, etc?

Thanks

I'm not finding anything via internet search.

This unit is new to me. I have a 645z on order and would like to have a remote shutter controller. Search yields programmable intervalometers for canon and nikon, but I don't know the compatibility for the Pentax. Also, I do not find dealextreme.

I'd appreciate a link to a unit that will work for this camera.

Thanks again.

i'm ordering a replacement for the one i dunked in the ocean. here you go:

0.9" LCD Wired Remote Shutter Release for Canon/Pentax/Samsung (1 x CR2032) - Free Shipping - DealExtreme

here's another:

http://www.amazon.com/Neewer-Shutter-Release-Hasselblad-PowerShot/dp/B003Q9X...release+pentax

what's peculiar about these is there is not OFF button, so i would reverse one battery to turn it off. eventually my battery door broke and i had a thick rubber band holding the batteries in place. just an fyi

I use the Pentax waterproof IR remote on a lanyard around my neck for tripod work.

Works great. AF not required as you do that when composing using the camera and the AF button anyway.

I went with a $20 Vivitar wired trigger. I skipped the intervalometer versions since that feature is in body, and I've yet to use it on my 3-year-old body anyway.
Be prepared to have to modify the wired remotes if you buy a non-Pentax version. The generic versions FOR Pentax all have a plug that's too big to fit into the hole in the 645D. I had to use a bench grinder to reduce the outside diameter of the head of the plug to get it to fit inside the hole. That wasn't a problem as there's plenty of plastic around the plug so I didn't have to worry about exposed wires.
