I have a blue "moire" striped Skyline, one of the first pens I bought from Doc Nib (he of the evil temptations!). I got it for roughly $60. It was a 3-pen purchase at, IIRC, $180 or so. The initial price on it, alone, was probably more like around $75 but he cut me a bulk deal. (Geez. I'm a bulk pen buyer. Now THAT's sad.) Anyway, if my experience is any indication, you should certainly be able to get a working Skyline in your price range. Look around at the websites -- I bet there are some post-Christmas sales out there!
I do see why people FEEL that the Skyline is fragile. Relative to other similar sized pens that I own, it's kind of "rattly" and flimsy feeling. It hasn't broken or anything, not yet, and I carry it around sometimes in my briefcase like an idiot, so I don't think it really IS flimsy, it just FEELS flimsy. There's something to this feel, however. It doesn't quite have the right "heft" in the hand, when you're writing. And I find that the lever doesn't stick down as good as it should. It flippy-flops open ever so slightly when not in use. Not so much that you'd worry about squirting ink, but enough that you kind of wonder, "Should I get that fixed? Nah." When you post the cap onto the back of the pen, it can catch the lever and lever it open (in the direction you definitely do NOT want the lever to go). Bad design, Eversharp should have thought of that. Or maybe they were thinking that the cap would "lock" the lever closed when you're using the pen, I dunno. It's a weird arrangement, different from any other lever-filler that I have.
Mine has a flexy nib. It isn't super flexy, just flexy enough that when people get my correspondence they go, "Ooh, he used a NICE pen didn't he?" I like that. In fact, I like an awful lot about this Skyline. It's a "user" grade (as are all my pens but one; some idiot gave me a nice pen, much too nice to use; so I don't give her Christmas cards any more; just kidding) and that's great. I think what I like most about Skylines is the wide variation that is nevertheless clearly explicable -- three sizes, plus the bargain version (missing the clip-band over the derby); several colors; plain and striped; etc. It's like making an ice cream sundae, you can choose whichever topping you want. And of course it recalls the great post-deco era of industrial design, like those trains that Jack Benny coursed through the country on, or those stub-nosed airplanes that Jimmy Stewart shot at Japs with. Very "vintage era" in look. (PS. We're not supposed to say "Japs" any more, that's not PC. I use the term only advisedly, as a deliberate reference to the argot of bygone days.)
Of course, all of the preceding is just a comment about MY Skyline, not ALL of them. I've only ever held this one. And yes it is a blue striped Skyline. And yes it cost me right smack in the middle of your price range. And no it's not for sale.
