I like my Analox O2-EII but it's not one of the cheaper ones. I've used other models like the O2 Quickstick, and one other, but I felt the Analox was easy to use.
I see a bunch of them at the dive sites and on boats... the way I see it, I see it more often than others for a good reason.

I use and sell this one - Palm O2 D Oxygen Nitrox Analyzer [aiipalmo2] - $265.00 : Chipola Divers, Sidemount, Technical, & Cave Diving Instruction & Mentoring
Easy to use and on the less expensive side. No need to buy a more expensive model. There isn't any difference between analyzers other than the outside appearance of them.

I bought an Analox analyzer when I got my nitrox certification, but sold it within a year as I wasn't diving nitrox much. My fiancee recently began using nitrox on most dives, so I bought her a new Analox O2-EII, $239 at

If you are of the electronic nature or know someone that is,, go to oxycheq and get an elcheapo for 100.00. Make sure you get the 10 turn optional pot with it.

this too is an option: http://www.scubaboard.com/forums/divenav/451314-nitroxbuddy-wireless-oxygen-analyzer.html
the cost savings is in using your smartphone as the display via bluetooth.
$129-$199

This is a great option if you have about 3-4 hours and have the patience to build it yourself. You will need to cut the holes in the housing and solder the connections. I haven't built one of these but I do know people that have. Personally, my time is worth the extra money! And I like building stuff!

I used to use an OMS analyzer that required a connection to the BC inflator and used a flow-meter etc. It worked just fine, but did require mounting the reg and "setting up"... It filled a small Pelican case, so was fairly large for travel when flying, so I tended to leave it at home, assuming the resort/boat would have one and it was working properly.
When the O2 cell died last spring (simultaneous to the LCD looking wonky on occasion), rather than replacing the cell, I spent the money and went to the Analox. It works just as well, and is easier to use since I can just stick it in the valve. "Easy" = more likely to use every time. (I lost a friend last year who failed to check a tank, oddly, and toxed out t depth, in a cave.).
I also picked up the Analox CO analyzer as well, and both fit in the case previously occupied by the OMS analyzer.
I think you want to steer clear of "uncommon" brands. The O2 cell will expire sooner or later, and you want to be sure replacements are readily available. When I did that, and also considered ease of use and portability, I went with the Analox unit.

One issue with analyzers that are "easier to use because you can just stick it in the valve" are that the flow rate of the gas from the valve can alter the readout. Too high of a flow rate will get you a low reading. The analyzer I use has that option but also has the quick disconnect option. The nice thing with the quick disconnect option is that the flow rate is always constant so I can count on the reading being accurate and I have an LP hose on all my regs so it's very easy to analyze.
I've had a few... All work the same, but there are idiosyncrasies with each:
Handi+ o2 Analyzer (Maxtec) - was originally designed for the healthcare industry, then repackaged for scuba. IMHO, one of the WORST analyzers out there. Very slow to read and you can't replace the O2 sensor. It's considered a "disposable" analyzer, and costs the same as many better models! Can be found for around $200.
Analox O2EII - the industry workhorse, you'll see this analyzer on almost every dive boat and shop out there. Very easy to use, easy to replace sensor, quick response time. This is my current analyzer. Can be found for around $230.
Oxycheq Expedition (and X model) - fantastic for mixing due to readily available remote sensor and sensor tee. Very fast response time. Housing is a bit plain, but at least it's black. Sensors are among the least expensive to replace (but we're only talking by a few bucks). I use this on my continuous blending system. Non-remote version can be found for < $200 in the assembled form, or $100 as the "El Cheapo II" kit. Similar to the design in Vance Harlow's Oxyhacker Manual, if you wanted to source parts yourself.
