Yes both.
My first MB 146 cost me about $200 with a life time warranty. My rollerpen was $70 (I lost that one). The recent MB I had (a gift) accidentally rolled off my desk and the barrel cracked. I found the modern MB only has one year of warranty (60 days on the nib) and cost me $35 to repair the pen.
So you are paying a lot for the plastic.
The nib on my Cross was skipping a little (a very underrated pen, nib is rumored to be mad by Namiki). I sent in for a repair and it only cost $7. Cross, Parker and Sheaffer all have lifetime warranty. Oh, the Faber Castell also has life time warranty.

This is my recent purchase. It's heavier than MB. But it writes well and feel pretty good and it's pretty reasonably priced.
