Hello and welcome.  There is no doubt that the Olympia SG1 is an outstanding machine, and I use mine regularly.  However, the thing is an absolute beast and you will not care to be moving it from one place to another very often - unless you are training for the next Olympics in weight-lifting.  Unlike Uwe, I am going to add a portable to the list of suggestions: the Olympia SM9, and I have very specific reasons for doing so, based on your wants.
Firstly, this machine is also outstanding in terms of mechanical quality - many would call it the best portable generally available in the market of used machines nowadays, and I think I must agree with that.  Secondly, it has a full range of features - more features, in fact, than some bigger 'standard' machines, and they are all well designed and engineered.  Thirdly (and this is a big one for me) it is very unobtrusive in looks and style, and I find this a real help in keeping me focussed on the writing.  I am never distracted by any aspect of this machine, and I almost always choose one of these when I have some serious stuff to commit to paper.
Good luck, and let us know how things turn out.

I will chime in also -- nothing wrong at all with Uwe's two recommendations. The only drawback to the Remington and Royal he mentions are that they require spools that are unique to those brands, and if those machines don't come with spools already, you may have a difficult time hunting down the correct ones. However, there are some excellent folks on this forum who may have some extras they'd be willing to pass on to you. Ribbon you can get, and you can load it onto the correct spools, tedious and messy though that may be.

I am another who would vote for the Olympia SM9. Maybe the best all-around typewriter out there, though I do love the large SG1 and SG3. Too bad you aren't nearby -- I have a wide-carriage SM9, without a case unfortunately, that I'd be happy to let you have gratis. I wouldn't want to ship it -- way too risky, based on the horror stories you can read here on this forum. (You want to drive to CT?)

  I'm a re-user of typewriters since 2005.  I stepped into the digital domain quite eagerly only to find that computers, while good for researching information, did not meet my creative needs.
    First was a Smith Corona 12 the same model I typed papers, library cards, and lecture notes on while attending college in the early 1970's.  Then I followed with an IBM Selectric III, similar to the one I used in the library.  Too similar to a computer so I begin trying out Olivetti's, Olympia, Underwood, and Remington.  I finally bonded with the Olympia SM3 and SM9 deluxe.
   Moral:  You will find a typewriter that you can bond with.  It will feel right when you use it.  Once you do, typing with a typewriter becomes a wonderful creative experience.  Try reading Richard Poult's book,  "the typing revolution".  Can't recommend it highly enough.

thank yall so much!
