In honesty from personal experience and trying to keep to a low budget... sentro 48 and 40 work wonderfully well great value for the money. However the 22 pin. I bought each broke within a few uses. The money I spent on 4 of those I could've just got the addi 22 to begin with. Instead I treated myself for my birthday to addi 22 but wish I'd have got that in the beginning. Its much better and accepts much more yarns I've managed to make and make and make with it. My next one I really want is the addi 46. I know now with the 22 being amazing the 46 will be even better!
