I bought these Kaweco fountains l ages ago when Peters of Kensington ran these out and got free shipping on ebay. I found these have smoother flow and less messy compared to the Lamy Safari's that I would put in the similar entry level category. The ink comes out a lot smoother too.
This is great value for the pen plus 4 cartridges of ink (around $5-7 worth).
Others include

I also have a Sport, it is the 'travel' Pen. It is a bit shorter, but feels just okay with the lid on. The Perkeo definitely feels better
No stock for Melbourne in-store pickup for most (if not all) of these :(
