I'm ready to buy 3 seats - Does any body know the price diff. between
the two ( non -powered ). How does the coaster hold up to every day
wear. also is the Berk that much more comfortable than the Coaster.
I'm also considering going powered - will the motor last, and if the power
motor breaks does that mean that the chair will not recline. I can really
use some help here. I saw 3 Berkline 090 -Powered for about $2000.
is that a good deal.

I think that the Studio chairs offer an amazing quality for the price which they can be had. If you are considering either the 090 or the Studio, I would actually consider the Studio to be the better buy *IF* you aren't concerned about options like Power Recline.

On the other hand, if you have found 3 090's with Power Recline for under $2000, that it is a very good deal, and would very much be worth it if the Power Recline function is something that interest you.

EDIT: I forgot to address your concerns regarding the Power Recline quality and life span. I, among others, have had my Berklines with Power Recline for several years now without any type of issue whatsoever with the motors. But, unfortunately, there are not-so-common instances where a motor can fail. Luckily, with the "plug and play" connectivity of the motors, they can easily be replaced. If your motor is out of warranty, you can always call Berkline and order a new one. They are fairly inexpensive, and I would be happy to give you the pricing for a replacement motor via PM.
