I do, you can see the post here: http://toptierimports.com/index.php?topic=3121.0
It depends on what you plan to do with the bike. CBR125R values have pretty much bottomed, so you could sell it for what you end up paying for it after you're done.
You will be left wanting more, simply. However the 125 is a great city bike and a great way to get your feet wet, since it is one of the bikes used in the training course as well. Once you get the hang of it, it is super light and flickable, and you can bounce off the rev limiter all day long without worrying. They are so much fun I bought another one just to zip around town on. I would not recommend it for any sort of highway travel.
Very easy to maintain as well, they take 1L of oil and have no oil filter. Simple engine.
Hope that helps.
edit: I notice this is a gen 2 125, which will have a wider back tire and some other small differences. Even more fun.
