There's a lot of wiggle room in an AIS selection and application. You are probably aware that there are two major distinctions in the definitions of AIS: class A and class B. You can eliminate a lot of consternation over your brand / feature selection by eliminating class B from the beginning...though class B may ultimately prove to be less expensive, it's not a developed product here in the US just yet.
Class A receivers and the more sophisticated transponder based systems used (mandated, actually) by commercial vessels and others with special requirements drive the industry. You, as a small, recreational sailor needn't be concerned with the ability to tell the world who you are, where you are, where you're going and how fast, where your GPS antennas are, etc, etc, etc...a lot of information of no use from a small vessel.
So an AIS stand alone receiver will provide all the benefit you need or want and then some. It will require a VHF antenna, probably mounted high like your radio...and for the same reason, range, although that could prove to be detrimental. Sometimes you can get too many targets vying for your attention. Yes, you can split with your VHF but it's not recommended.
I have no specific experience with Sitex , but I prefer to see AIS data presented on a chartplotter...just my opinion
What ever you do, or with whom, go for it...AIS is an amazing, absolutely amazing technology
