I would suggest that you try before you buy ( especially the cheaper models ).
Some time ago I had a project to make a clock and I thought a scroll saw would be useful for crossing out the wheels. I bought a cheaper model and in all honesty it was not suitable. It was very noisy, quite a lot of vibration and difficult to make accurate cuts. Luckily I practiced on spare pieces of brass and convinced myself that this was not the tool for the job. I bought a piercing saw and made a satisfactory job of the crossing out! I shoved the scroll saw into a cupboard where it languished until recently when my son needed something to cut thick cardboard for a work project he had. It did this OK but , as he lives in a flat, he was very bothered with the noise it made. Now mine WAS. a cheap model and maybe a better quality version would be better.
Hope you find something to help with your projects but my advice is to try it first.

PS
Looking back through the forum I see that I have posted on scroll saws before – and am consistent in my opinion! The only difference in this post is that my No 1 son has now found out that it doesn't work for him either.
