While it won't help answer your question, the exact opposite was raised in a recent thread.

On eBay in the UK, 500 series kit seems to be selling for ridiculously high amounts, regardless of whether it is working on not!

I'm currently looking for a pair of 5200s in the UK. My research has shown that over the last 3 months or so, sold prices seem to be around £2100 on average for late serial number SL versions.
