    MIke Zagielski, at foredom can give you the details of
    interchangeability of handpieces..(Blackstone industries / Foredom
    Co.).

    But their are alot of micromotors out there and many cheaper witha
    longer warranty.

    however, I love hammer handpieces, and feel incomplete without one
    (or two)..and a few shaped anvil points and a diamond tip..so go for
    the cheaper,carbon brush model if NOT interchangeable..just buy the
    brushes as spares whrn buying the unit..perhaps use it as a
    bargaining point ( if you throw in a set or two of spare brushes you
    have a sale- type telephone conversation)..However, many hammer
    handpieces are not universal, so do do the research..

    Foredom direct also has alot of sales this time of ear so check that
    link first before going through a middleman supply.

    Also DON"T OVERLOOK Canyon State Dental Supply..right now they have
    two great micromotors one on sale for 299.00-799.00 or there about,
    that is not only high torque low speed but variable and reversible
    speed..and runs very cool after hours on hours of grinding, carving,
    hamering etc. ( i just sent them back a#700 series test unit !- loved
    it's reversible feature, and the run time, as well as the
    ergonomically correct handpiece and carbon pile foot pedal..and
    SELF_DIAGNOSING features the price was another factor that made it
    attractive,and that it comes with two handpieces,one a hammer type
    but the anvils will need modification for jewelry purposes- if you
    want to modify them, I guess).

    I personally would rather change brushes for a few reasons If you are
    a beginning jeweler:..they are a great indicator of the way you use/
    are using a tool, and when maintenance is needed..I have had sealed
    brushless motors, and micromotors ( abeit proxxon ) in the past, and
    there was no indication that the units were on their way to death
    from overuse...or when it was time to change out a core( on the
    flexshaft) or other simple, oft overlooked maintainence details that
    would have been easier with a simple turn of a button and brush
    examination.. and if you do opt for a micromotor you may want to
    consider checking globalspec.com, or their vast assemblage of
    micromotors and parts primarily intended for a dental audience but
    the two arts are so close that all products are interchangeable
    between dentistry and goldsmithing.. 

    I have used Buffalo dental micromotors before ( brushless) and for
    about 400 bucks,with an optional 140 dollar hammer handpiece- though
    both are in the gulf of mexico presently, they worked fine for about
    a year or two!!
