It's a Manfrotto Nano VI - but I'd probably pick the VII because it gives you a bit more space without adding too much to the bulk of the thing. The camera the VII is made for is the GF1 with 20mm lens - should work out perfectly for the M3 and 22mm ...
I never did find out if she took the trip.
I was once present when a Big Box Software Co. Sales Associate who landed our company as a contract got awarded a free trip to Australia, which she could take on the following US Summer. She was thrilled, until someone pointed out the seasons were reversed Down Under. She already hated the NorthEast Winters.
You can use whatever you like, really - the idea is to stick with it; the Pen F with 17mm f/1.8 would certainly be fine (I used a E-M10 with that lens for my first SiJ). I've listed the LX100 for now - great tool for the job. I tend to up the ante by using a single prime, but that's not compulsory (except from participating and contributing, nothing really is - and even then, you can drop out, no hard feeling).
You don’t have to post everyday. The shot must be taken that day but, for example, you can post a few days later. There is usually a separate thread for each day. Your proposed combo would be an excellent choice.
I did something similar for the challenge a couple of years ago, Olympus E-P5, 17mm F1.8 lens and sooc only, no editing. It was hard! 31 days on the trot, composition became vitally important.
