    For what is probably the best manual fret saw frame see: 

    http://www.hegner.ch/frameseten.htm 

    This is a Swiss site for Hegner who also  may well make the best
    electric scroll saws. Hegner is sold in the US by Advanced Machinery.
       I don't know if they sell the manual saw, but Switzerland is on
    our small world. They are EXPENSIVE .  Everyone who has one swears by
    them.  If you are making money with your work really consider the
    Hegner. I don't have one but have a couple of the asian knockoffs 
    at about 1/10 th price. one is a vari speed 400-1800 strokes per min
    and the other is one I modified to about zero - 400 strokes per min
    with a longer adjustable stroke to use more of the blade. I use this
    one to cut up to 1/2 " 6061 T6 aluminum tooling plate. The best
    blades are the expensive ones and  even then they don't last
    spectacularly long  on this type cut. 

    The short stroke on the power saws is one thing that causes the
    apparent slow cutting. Broken blades are  caused  by  pushing the
    cut and twisting the blade as well as trying to use a dull blade.
    Cheap  blades have poor quality control and are often very hard or
    very soft as well as not very sharp. 

    For fancy cuts on smaller and thiner material  the old bench pin and
    saw frame is probably better than a power saw. 

    When using any tool I find it best to either fix the tool or the 
    work. Trying to control both at the same time leads to poor results.
    Manually gives much better use of the blade length. For a manual
    guided frame The Bonny Doone  one from Rio or direct from Bonny
    Doone is probably your best buy. If these don't work it is either
    poor blades or poor operator.
