Recently I've been thinking of an Apple Watch purchase. I'm thinking of a used/refurbished 1st gen model, mainly because I don't want to spend alot of cash initially until I try it out. I've read/watched quite a few reviews but Ive got a few questions. Where's the best place to look and get a reasonable price, or would waiting on the holidays be better? 38 vs 42mm? I'm leaning toward 38, as I've never worn larger watches. I'm concerned about the smaller display size. Thanks for the feedback. I really appreciate it.
