So I'm considering enrolling in either GE or NEXUS.

It looks like NEXUS is a little cheaper, although I don't travel to Canada often at all, so I don't really need it. I might travel to Canada more if I had NEXUS, as there are some places in Canada I'd like to visit. I don't have anything that would disqualify me for entry into Canada. Plus, having NEXUS does double as GE for US immigration purposes.

On the other hand, although the initial fee is a little more expensive for GE, I can probably schedule the interview with much greater ease since I live about 25 minutes from DEN. To go NEXUS, I'd have to plan a trip specifically into Canada for the interview.

So to sum it up, GE is a little more expensive but certainly more convenient. NEXUS offers more travel options, but is a bit of a pain in that it would require more of a dedicated trip just for the interview.

My next international flight isn't until January, so time isn't a huge issue yet. Are there any compelling reasons I haven't considered to choose one option over the other?
