Some more electronic comparisons...

In 1970 I bought an RCA TV for $500. In 2010 I bought a Vizio TV for $500. The Vizio is miles ahead of the RCA.

In 2001 I bought a Dell PC for $1300. In 2009 I bought an HP Laptop for $450. The HP has far more features @ less than 1/3 of the price.

Interesting how some electronic devices have increased in price, while most have decreased, and some stayed relatively the same. All this while parts, for the most part, needed for assembly have become cheaper. I suppose labor is a big factor in electronic pricing. Thus the Casio made in China, costs less than the Yamaha made in Japan.

Also Tony is right...supply and demand is another factor in setting prices. Everybody has a computer and a TV with lots of competition. Arranger keyboards, without much competition (Gary is right) are a specialty item, made for certain people, who are all too willing to pay top buck for the latest.
