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.
