Eco makes for a great first pen or Nth pen. You get a well-made piston filler and a relatively lower price with various colours as well as nib options. Plus with its clear barrel you get to see the ink sloshing around. 


With each TWSBI pen, you get a toolkit that allows you to easily disassemble and reassemble the pen for maintenance/cleaning.
