So lemme expound at (too much) length on what's worked for me, and maybe it will help.
Thanks for the detailed response, it's very helpful.
I started geotagging my photos somewhere around 2005 using a Sony screenless GPS that just saved track logs that I would clip to a pack or my tank bag on my motorcycle. Then I used software (I forget which) to tag the photos from that. Unfortunately I'm a very disorganized person, and I was taking photos because I was traveling, not traveling to take photos, so sometimes the photos would be left on my camera for months and if I wasn't careful, I would lose the track.
I had looked for cameras with built in GPSs, but at the time it was only very expensive stuff for certain narrow markets like surveying. In 2008 Nikon came out with the P6000, their high end point and shoot, and as far as I know, it was the first consumer grade camera with a built in GPS (of course, in 2008 the iPhone 3G also came out and it had GPS to geotag photos.). So I snapped it up as soon as I could get it, and that was my camera from 2008 until about three years ago--the end of 2014. Nikon always had kind of bad GPS implementation. It could easily take several minutes to get a lock, and it the camera was moving around it couldn't get a lock, so about 70% of my photos got tagged. Their current implementation doesn't seem any better. The only difference is they allow you to download AGPS data for a two week block, load it on the SD card, and the camera can get a lock quicker.
In 2014 I bought a Nikon S9700 because I was taking a trip to Rome, and I was hoping 7 years would get me better technology. I hate that camera. I'll keep my P6000 around as a pocket backup, but the S9700 could break and I wouldn't care. Now I'm planning a trip to India next year, and I decided I needed to get a good camera, and having had film SLRs in the past, I decided it was time to invest in my first DSLR. As far as options, there aren't many that don't rely on a dongle (which I wanted to avoid.). Sony did it once with the A99, Nikon did it once with the D5300. Canon put it on the most recent 5D and 7D (and it looks the the new 6D will get it as well.), and of course Pentax K-3II, and K-1.
I started by figuring I would get the D5300. Its very affordable, I've always been a Nikon guy (still have my Nikkormat FTN and a bunch of great old pre-AI Nikkor lenses.). I couldn't afford the A99 or any of the Canons or the K-1. The K-3II was a stretch for me. There were a lot of features on it I liked, and I had shot friends K1000s in the past, so I had a lot of respect for Pentax. So I started leaning toward the Pentax, then I found a video review on YouTube where the reviewer claimed less than 30 second location acquisition. That sealed the deal, so I ate nothing but ramen for a month to save up the money and order the camera, all the while hoping the reviewer wasn't exaggerating. When I got the camera, I sat out on the porch when I first turned on the GPS, and timed it's first acquisition in this hemisphere--28 seconds. Now that it knows where it was last, acquisition is always less than 5 seconds. Nikons GPSs feel like my 2000 Garmin eMap, this Pentax feels like my modern Garmin Montana when it comes to first acquisition.
