hi folks
im thinking of upgrading to either a bandsaw or a scrollsaw and as im going to be cutting mostly hdpe and polycarb i was wondering if anyone on here has some advice about what to look for i work out of a corner in my bedroom so smaller would be better and im not loaded so not one that costs thousands

im mainly looking for one as i have wasted lots of material with being unable to cut a straight line for a variety of reasons and im failing hard with the jigsaw in general though that could just be the blade

thanks muchly
