I had a pair of Schwalbe tires that I quickly put on a bike I sold on craigslist. They were the cheaper Marathon GG offering, i believe. Felt like plastic, very rigid, and very slow moving.
My wife has Schwalbe tires that are light, supple, and feel quick when riding. Shock- they werent the cheapies.

2- As for 700c tires internationally- just look into where you are riding first. 700c tires arent a rarity in heavily populated areas of developed nations. Perhaps the specific tire you want isnt available, but some 32c or whatever size should be readily available. Bring an extra tire if you are going out of the country, sure that makes sense. Bring a tire boot too though...weighs almost nothing.
