Sweet vs. Sunshine (16's)
 

Have you tried them both and bought one over the other for some reason?

The Sunshine http://www.sunshine16.com/ is an affordable simple machine. The Sweet http://www.handiquilter.com/product/hq-sweet-sixteen/ is computerized and you can add a stitch regulator. Oh, what the heck.. who has a Bailey http://www.baileyssewingcenter.com/bahoqupro15.html and uses it as a sit-down to compare?

is sunshine a sit down or can you use it on a frame

I recently bought the sweet 16 and love it!!!! I had no training or even a demo & I was able to put it together & thread it in less than 30 min but do use superior threads like king tut!!

I never saw a sunshine model. I compared the HQ to the TinLizzie. My purchase (just last month) was the Sweet 16 and I love it. Decided to get it with the TruStitch regulator module. Boy, it's like learning to drive a stick-shift all over again lol. BUT I finished my first quilt 38x38 DP9 in a basic meander pattern in about 3 sittings. Not bad for someone who only did SID before.
