Folks:
I am going to start a few projects which will require the construction of aircraft mounting struts (think Mistel) using round styrene stock. Probably no larger than 3-5mm in diameter. I'll need consistence angle cuts plus a mitered edge.
So in your experience, what has been more effective. A purpose built device such as the NWSL Chopper (http://shop.osorail.com/product.sc?productId=278&categoryId=15) or a stock miter box and the appropriate saw blade.
Thanks

Jeff and I were just discussing this. We've both been less than happy with the Chopper II (the all metal version). Micromark sells their own version of the chopper you linked, for a lot less: http://www.micromark.com/chop-it,9547.html (http://www.micromark.com/chop-it,9547.html)
I heard of people praising the Chopper's "precision", but I've found it not to be all that precise (cut to the same length or angle repeatedly) nor accurate ( a "45 degree" angle cut won't be). If you want a bunch of strips that vary from about 22-25mm long and 45-ish degrees, then it's fine. Otherwise, a miter with a thin blade and a good guide would probably produce better results. Something like this: http://www.harborfreight.com/bench-top-cut-off-saw-42307.html (http://www.harborfreight.com/bench-top-cut-off-saw-42307.html)

Pretty much sums up my own experiences with both versions of the Chopper that I have. The blade flexes too much during the cut stroke is what I have noticed. This is only aggravated by the flexing of the cutting arm. Then you have the comedic system of securing your cutting guides with a very weak device that does not hold fast when put to the test. The cutting guides would move out of angle with minimal influence. If you absolutely have to have one of these things then do so but given the simplicity of the design and the lack of rigidity in performing accurate cuts you will not be making much in the form of precision work.

I have one of these. It works great for cutting brass rod and tube as well as styrene. Micro-Mark also has one but it is considerably more expensive. You can also order the Micro-Mark replacement blades and cutoff wheels and they fit the Harbor Freight saw. There is very little flex or wobble when cutting with this.

Thanks For all your comments and suggestions.
If any problem can be solved by the purchase of another Power tool, then there are no other options. :)
