Which esc and servo for my b44.1

[Scheuee]

Hello I am coming back to the sport after a 17yr gap, I am after an esc was thinking of possibly going second hand, looking at the Novak sr pro or a lrp.
Also thinking of a servo a savox 1258 or an associated ds1015 are these any good I used to use ko but they are silly money now.

If it makes things cheaper I don't mind importing one if you could send me some links.
Thanks all
