I'm a first time AW buyer and deciding which one to get. I'm trying not to spend too much to first see how much I will like it and use it. I found Black Aluminum S2 refurbished on apple website for 279. Then I found for 395 open box SS Black S2, new ones are 429. Or new Black Aluminum S3 for 359 (no LTE). The only reason I am thinking about SS is saphire. I had mechanical watches with and without saphire, and have to say, the saphire ones are much better, no scratches, and i do manage to bump them against the wall, bricks, bridges, god knows what else. I was thinking maybe regular S2 with applecare+, for 320. Or S3 with applecare+, then i am at 410. For SS S2 i wouldn't then get applecare. What do you guys think? You have more experience with performance, scratch resistance, other factors..
