You left out Pink Floyd. But some other great Brit bands that are more obscure is Van Der Graaf Generator, King Crimson, Blind Faith, Jethro Tull, Jeff Beck and Traffic
The most I ever paid was $300 back in in 1982 for a Pocher Bugatti Type 50T. It was a bargain at the price. It had been marked down from $450 at KayBee Toy & Hobby shop at the mall. The next one does include after market stuff on because the aftermarket goodies for this kit cost a lot. The is the Tamiya 1/12 scale Porsche 935 ($75), that was in the early 80's. But in 2005 I bought the Scale Motorsports superkit for it which was $535.
