Anna,
I've had many quilt machines since I started quilting back in 1994. A Ken Quilting machine, Nolting PDQ, Gammill Quilting machine, & APQS Quilting machines, and so far I like the APQS machines the best. Their light and easy to use. I have two at this moment & wouldn't sell either one. As for yourself, you need to go and try as many as you can to see what's best for you. Buy what you can afford and buy the biggest one. Buying smaller will just make you wish you had bought bigger the first time around. Good luck, zeke..............
