Steel Sub was my first watch, and I Love mine! Steel Subs hold their value too, mine I can sell today for more than I paid for it a year ago. This cannot be said for a lot of other watches.
Great watch. I say "go for it" but I'm biased. IMO you can't go wrong with a steel Sub, even if you decide you want something different later, you can sell/trade it without much, if any losses.
