There has been lots of good advice offered so far. I would recommend giving a good dealer a call and talk through your requirements including budget, terrain, and usage. Tom at Night Goggles is a wealth of knowledge and a sponsor here 909-312-5424 X531.
The PTS233 is OK as long as you are not shooting or scanning much past 150 yards and you don't have a lot of humidity. If either apply, then I would look for other options. The 536 is a nice scope for open field hunting where you are consistently shooting past 100 yards. I wouldn't recommend it for cover or anything where you need a wide FOV. In the same category as the PTS233 is the Pulsar RXQ30. Similar quality, FOV, but just a little cheaper. It doesn't have recording, but very similar to the Flir PST233.
XM30: The 4.1x native magnification is going to be a lot. I would lean towards the Pulsar Helion XP28 or XP38. Unfortunately, the XP28 is being discontinued by Pulsar, so you may need to go with the Helion XP38 depending on timeline. The Helion XP38 is a very versatile scanner.
The Wraith is a decent entry level Night Vision device. One of the nice things about it is if you decide to eventually go thermal, you can use it during the Daytime as well, which is how I use mine. You can get to about 150 yards at night with the stock IR. It is 4x native (base) mag so for cover, brush or tree hunting again it is not ideal, but a relatively low investment in comparison to thermal.
The following comment is one that I used to say don't do, and that is buy a thermal scope that can also be a scanner. The reason I typically say that is the scanner is what you are going to use 98% of the time, so why sacrifice trying to scan with a big, clumsy scope. However, my recent experience with the Bering Optics Hogter-R is starting to change my mind. It is smaller than my current scanner. There is a 35mm and 25mm option so 2x and 1.4x native mag on those two scopes. You could start out with this and a Wraith for instance. You will most likely quickly want more thermal, but by doing this the Hogster-R could be a scanner and/or your scope. If you hunt with a buddy, both of you could have shooting options as well. If you don't need internal recording, it is a great value. I will have a review available on this unit soon.
