How much are you willing to spend? My first REAL fountain was the MB Starwalker in metal and rubber. I love it, but it also cost over $300. Lamy's are great. Just make sure you get a chance to write with the different nib sizes before your purchase. A medium nib is a different writing experience than your 0.7 gel pen. Fine nibs are more like the G2, but the ink doesn't tend to flow as smooth as a med nib. You get the point.
