Check the prices for the Thunder 1A - five years ago you could find them for under £100 - they're now selling for upwards of £300 on eBay. The neck thru 11 and 111 series are now selling for £700+.
Similar story with BC Nanyos which are finally starting to realise prices acknowledging how well built they are. Rarely see them for under £100 anymore - I think I've bought at least 4 in that ballpark.
I think that both the above will be good investments for the future - if there is a future that is...
