We’ve never had a problem bringing our limit of stuff packed in suitcases back from the US or wherever we have traveled. And we’ve brought some odd stuff…ceramic fireplace logs, a bread machine, and of course…linens and towels (you’ll spend less and get better quality stuff in North America.) However, everything you bring should be for personal use, including electronics. I’ve found that usually means I can get through with two laptops, camera, video camera, ipad, and phone. There are rumors that Ecuador customs wants to get more serious about the amount of electronics coming in but unless you’re trying to bring lots of stuff for resale you should not have a problem. We also bring spices, Ranch dressing mix and that sort of stuff that’s hard to find here. You might have a problem bringing seeds and plants…that sort of thing. For alcohol I believe the current rule is 3 liters per person — that’s what I was told in Panama duty-free a few weeks ago. (We brought 5 between us, no problem.) And if you enjoy alcohol, I definitely recommend sticking up in duty free on the way here…on fine spirits, anyhow.
