I am assuming you are talking about a
juice fill port. The only
top port tank that I am aware of in your price range is the Cartomator Delrin
tank sold by Vaperfexion for $23. You can choose between polycarbonate plastic or glass tubes.
The Cartomator Delrin Carto Tank - Vaperfexion
I believe you have to get up into the $55 - $80 range for other tank options:
Vaporfexion also sells a couple of more expensive tanks with a top fill port:
The Prov-V Cartomator is $58.
Pro-V Cartomator SS - Vaperfexion
The Pro-Vex and Pro-V2 are $80.
The PRO-VEX and PRO-V2 - Vaperfexion
Avid Vapor has a couple of Kir Fanis tanks that utilize a top fill port. The Trap tank is $55, and the Tripolitis* is $60 (*uses a stand length cartomizer).
Tank Systems - Avid Vaper
All of the above tanks use a polycarbonate tube that would not be safe to use with cinnamon or citrus flavored juices. I believe Vaporfexion is offering glass replacement tubes for their tanks as an accessory that will allow one to use those flavors.
There are some vendors that use a
side feed port. Valley View Vapes sells a Sidewinder tank.

There are likely others that ECF members may know of.
