Any opinions on eKit SIMs?

Not sure of the difference between the 2 ekit international sims you mentioned, but can comment on Ekit. Bought a single country Canadian Fido sim card directly from them about a year ago, and they shipped quickly with documentation (needed the phone number in advance of a business trip). While their website isn't quite as polished as some other vendors, they do have good deals on some of their sim cards and sim/phone packages. Also they offer discounts if you enter through another website they have an agreement with (used Lonely Planet's link for my order, although from what you've said, it looks like purchasing through ebay offers some of the best deals for their sims).
