Which standing tubes have round/smooth tops and where to source them?

[alex nolan]

I'm relatively new to the nixie scene, but I already love these neon tubes. I'm really interested in nixies with smooth or round tops though. I have some IN-14s just to prototype with, but I'd like my finished product to look more polished. I'm aware of IN-18s, but not quite comfortable with spending $40 per tube. What are some other good nixie tubes of this style, and where is the best place to get them? Should I keep scouring ebay?

there are ZM1040 which look much much better than IN-18s but cost a bit more. If you want cheap round tubes then i got bad news for you. You could also try the end view nixie tubes, the small ones are still relatively cheap ZM1020 and equivalents, but good luck getting ahything bigger than 2cm digits on those.
