I'm brand new to this obsession having acquired my first typewriter within the past few weeks. I'm quite taken by the appearance of many of the machines but particularly those in the portable or ultraportable category. 

Here is the current stable in order of adoption.
1) 1946 Smith Corona Sterling in two stripe "Tuxedo" Black. I have to be honest, I fully intended to paint this one glossy black or a deep glossy blue but having seen it in person that is extremely unlikely to happen. It initiated me into the world of typewriter repair and now functions quite well. My typing technique on the other hand needs considerable work.  
2) 1930 Corona 4 with in Duco Black with black crinkle panels. Again this was intended to be a repaint but the black paint shines like is was applied and buffed yesterday. We are still making friends as there is a good deal of skipping going on and the carriage only moves one space at a time when the tab key is depressed. Regarding the former I suspect the escapement is tripping too early in the keystroke but we'll see. 

The next two are being shipped to me by a friend so I'll have to wait to see how they look up close and what repair or tuning lessons they have to impart.
3) Gossen Tippa. I read good things and the form factor appealed to me. The weird reddish crinkle burgundy not so much but you know how it goes. Once I hold it in my hands I may fall for it as well.
4) Optima Plana in sleek gloss black. This was strictly an aesthetic purchase. I hope it looks as beautiful in person and turns out to be a decent typer.
If you've typed on any or all of these I'd love to hear your observations.

My question is this. If I wanted something that had a different, but not inferior, typing feel to any of the above what would you recommend? I've read that some Erika models have a particular feel. Would that be true of an Olympia SF Deluxe, one of the Spendids or a Remington Rand Model 5? Should I seek out a Groma Kolibri or a Hermes Baby/Rocket? Others?

I'll acknowledge up front it will need to appeal to me visually. Life is too short to spend time with an ugly typewriter.

Thanks in advance for sharing your thoughts.

Take care,
Brent
