need advice/rant-new piano problems/location of good piano tuning schools

[Cynthia Ann Anderson]

I must first say that I am a layperson lurker, not a tuner/tech type.  
But, I truly have enjoyed and learned a lot by "listening in". I joined 
this list because I enjoyed the recent tuning/temperament discussions 
and other topics with Ed Foote and others on piano-l.  I was also hoping
to get some information w/o the sales hype to help me in choosing a 
piano.
 
I am a public school band director by trade with a limited budget, and 
ended up getting the Young Chang PE 121-(48" Pramberger model).  I also
ended up having to order the piano to get the finish I wanted-so I 
didn't hear the actual piano before it was purchase (yes, I know).  
When the piano was delivered it was grossly, unplayably, out of tune 
with several "buzzing" notes. The store sent somebody out 10 days 
later. After he finished tuning, while the front was still off, I told 
him about the buzzing notes--they didn't buzz any more-good, I thought. 
Immediately after the guy drove away, I noticed the same buzzing notes, 
some double striking hammers, and rubbing keys. (I was proud to have 
tracked down the source of the buzzes--they were loose screws in the 
fallboard hinge. That's why they didn't happen with the front off) Why 
the tuner didn't catch these things I don't know. I'm going to call 
back and have the store send someone out fix these problems. My 
thinking is that the store didn't do the needed prep work and are only 
going to regulate the piano to the extent that I notice problems and 
nothing else... My question is, what should I be looking for?  What are 
regulation or other problems often seen on this type of piano?  Any 
advice would be appreciated.

I also noticed that several black keys have clearly visable little 
circles on the front. It looks like the keys were not finished out 
correctly.  What are they?  And,can/should they fix them?

Listening to your discussions has also made me consider becoming a 
tuner/tech myself. It can't be any harder on the ears than the 
beginning band classes I teach. :) Are there any good training programs 
near me?  I am in the Dallas/Fort Worth area.
