I have a 430 that I purchased 6 years ago new. It has been a really wonderful workhorse for me. I will probably keep it until either it or I die! I have the stitch regulator which I used until I got my longarm. It did not come with the machine. It took a bit of practice, but it was fine once I got the hang of it. That is a really good price for that machine with the warranty. I have found the Bernina service at my lqs to be very good.
Mine came with a carry case (heavy fabric), a plastic case that attached to the machine with feet, bobbins, needles, tools and oil. I had to buy a few other feet and a single hole stitch plate. You might ask about those things.
