I (also) bought 3 extra ''insert pieces'' on which the cart need to
be fastened. With the included one this means 4 headshells.
I have seen one Orsonic on eBay for $300. This is the right
perspective to judge the prices. Anyway each headshell should
have ''movable 4 pin connector'' for azimuth and eff. lenght
adjustment. Those are not cheap. My only problem with Arche
are the headshell wire. If those are too tight they influence the
working of the SRA adjustment .
