Welcome, Matt. Allow me to be the first to lay down the welcome mat. (Yes, we are all THAT funny!)
You'll likely get all kinds of opinions on this one. There are threads on this forum that discuss whether the Bonneville is truly a "starter bike" because of inconsistency between its overall quality, and certain out-of-the-showroom upgrades that some feel are immediately needed.
I love mine, and feel like its not only a good starter bike, but a good keeper. I've done things to make it more comfortable and handle better, but I loved it also the way it was before I did those things.
Truly, I believe your starter bike should be what you're drawn to and feel comfortable handling. I believe the MSF course prepares you for riding
almost anything, and how you ride is up to you and your willingness to learn the bike's handling and power characteristics. Other's will certainly chime in on that statement, however.
You're looking at the T100 and you like it, don't you? Hmmm? Go for it.
