it would be much more cheaper and tone friendly if you bought a new neck.

I think around 20£ for a pretty decent one?
A new neck is probably going to run at least $150 US, whats that like 70 in english pounds
A refret is anywwhere between £120 and £160. You could easily get a really nice neck for that money but I think you might struggle to get a strat neck with big fret wire.
I could do the refret for you with BIG wire for like £70 if your willin to cover postege too.
