i was needing some help on which scroll saw to buy,,,i would like one with the quickest blade changes ,,and where the arm raises up,,to be honest i like the excaliber,,but it seems like they have got alot of negative reviews,,plus i cant seem to actually find new ones for sale,,most are reconditioned,,,and im kinda scare of that,,,i like the pegas,,,,but the excilaber just kinda sticks in my mind,,,can anyone give me some advice on the excaliber,,or for that matter on any scroll saw
