My Sweet 16 is almost a year old (February) and I love it !! Very easy to use....if you practice enough to get your stitches consistent, most people end up not really needing the stitch regulator. My dealer also drove my new machine to my house and set it up, no charge. HQ support people are very good, even called me to make sure setup went well. I haven't actually had to use the support people for any problems with my machine.
I agree with someone else's comment above - DO get the overlay. I also splurged on both extension table sides. LOVE the amount of space you get with those. Watch HQ site, as sometimes these side extensions go on sale.
Good luck !
