I'll also be staying with the 552 on my carbines.
The only advantage the 553 would give me would be that it uses the same batteries as my weapon light. Regardless this is a non-issue for me because I have a lot of other things at home that use Lithium AA's so I will always be stocking them.
The built in ARMS mount will actually limit my mounting choices and I also prefer an absolute cowitness and like mouting my EOTech directly to the rail. If I ever go with a riser/QD mount I will be getting the LaRue EOTech mount.
The 553's tethered battery compartment is a neat feature but it's not something that's an issue with me.
At this time the 553 is not worth the extra cost over a 552 to me. It will not do anything that my 552 can't do and would even limit certain mounting options for me, YMMV.
Stickman,
You aren't cheap you're just being sensible, why pay for features you don't want or won't use...
