It depends on how much time you're going to put into the quilt top each week. I've made shoe boxes full of yo-yos while relaxing watching tv, at meetings, at doctors offices, while having visitors over. It's easy to do and yet still pay attention...at least while using the Clover YoYo Makers...I HIGHLY recommend them. Well worth the $5-8 they cost.
They're available all over but here's a website I found that has prices when I googled Clover YoYo

Otherwise search yoyo or clover on the QB and you'll get lots of topics which endorse the plastic template.
