I agree with Floisme that the leather biker trend has peaked, a few years ago, so if being on trend matters to you, then I wouldn't bother considering the cost. A large portion of the board seem to disagree with this though, and of course if you want one and they suit you, then you should go for it regardless. Age also irrelevant.
They do however have small but significant fit variations though, and my normal recommendation would be to try loads on, then if cost an issue, find on eBay. (They are always on eBay). Mainly whether they are boxy or fitted, and where they hit your waist or hip tends to make a huge difference.
I wouldn't necessarily discount suede, but that makes it a different proposition completely IMO. I'd think of it more in the knitwear level of durability, or occasion rather than every day rotation. Not a jacket you could take off and throw anywhere, not worry about stains etc.
