Congratulations on your new machine, I bought my Juki TL98E around 15 years ago to use on my Little Gracie quilting frame, and she still runs like a dream, never had a moments trouble with her and her stitches are always beautiful, no tension problems ever. I did think of selling her after I bought a Qnique 15Pro to put on my frame a few years ago but I just can't part with her for so many reasons, so I set her up in the basement and use her to put my bindings on and quilt smaller projects.
I hope you get over your UTI soon, definitely not fun havning to take the medication for it, it sure didn't agree with me last time I had to take it.
