yamaha "soft close"

[Mike Spalding]

Don,

It will be one of the alternatives offered.  But since she specifically
asked about a "soft close", I want to include info on that also.  I would
really like to know what QRS has, how it works, and what it costs.  Anybody?

thanks,

Mike

PS  One of my really big pet peeves is merchants who, when I ask for what I
know I want, try to steer me towards something else before they've given me
any info on the product I asked for.  So I will not do that to my customer.
