If we could have the EX-Next internals in a new Esprit I'd have one, especially if they worked with the new 420 receivers.
I've been using an EX-Next for a while, but I only picked it up as I couldn't find any new Esprits in stock.
It'd do well in the UK, Sanwa stick radios are hard to find new now, which only leaves the Futaba 4GRS or the mega expensive Futaba with the big colour screen.
£600 would be a fair price over here for a new Esprit I think.
