Grand Action Dolly(s)

[Avery]

Does anyone know how much this action dolly from Jansen is? I can't 
find the price.
Weighs app. 23 lbs.

Laroy's is $349.00 but it has bedding screws to be able to duplicate the keydip
while out of the piano and even has a string height target thingee. 
Weighs app. 18 lbs.

Except for the things mentioned above, both seem to be similar as far 
as design is concerned.

I'm thinking about getting one or the other. I'm getting old! :-) So 
far, the Edwards looks
better because of the bedding screws and string height "target".

Anyone tried both of them? Thanks.
