hi karen dont know about the sealey , how are you finding the machine ? i brought a sip which is more or less the same but couldnt get on with it , i dont want to sound doom and gloom but if you really get into the hobby i would reccomend a hegner saw which i decided to get , base model is 375 if you can afford it i never looked back when i got that and i make and sell crafts in my spare time simple designs but effective angels etc,
i hope you get on with it ok but the difference with a better quality machine is worth the money you can find used models of hegner on ebay for a couple of hundred , then again you may get on ok with the sealey.
al the best mark
