for the price, having a 50mm 1.8 is well worth it. The length isn't bad at all, and having something with that low of an Fstop for that price is golden. I picked up my Canon Mk I for like $120 (Mk I is a WAY better lens).. and it is easily my favorite lens (granted my other 2 are the kit and a crappy sigma tele). I doubt the Nikon market is any different than Canon, so you should easily be able to sell it for what you bought it for if you'd prefer the 35mm, but I say get both.
