Hi Todd welcome to the village first of all The Torx is a nice machine but not for the scrolling we do it is fine to cut crooked lines in 2 and 3" material but not for material 3-5MM thickness and radius cuts of even less, second the rockwell 405 is a good machine from what I have read so far but I'm not sure if it comes with a pinless blade attachment, if not your going to be forced to use pin type blades which in our case again useless. Unless off course you have no intentions on making internal cuts. then the pin type are fine. I just not certain of what is available to you as far as machines go as we live in opposite necks of the woods I know your on a low budget so here are some names of north american scroll saw companies that you may be able to find where you live, now these are low end machines but will serve you well for a long time and they do have blade attachments available.
Delta, Black and Decker, Bosch, Makita, Sears, Dremmel there that should get you started so a 14-16" should do fine for starters and make sure you get pinless.
Goodluck Todd
