Radiator troubles - replace or fix?

[VTEC@14.7psi]

eyz all, my radiators been leaking from the top, i think is that the "top tank"?

u can c in the pic where the fluidz ended up

i read ppl say that u can just take it to a radiator place n they can repair it?

i got a quote for 320 for replace n fit, can anyone tell me if this is an ok quote and if it can be repaired, is it worth doing over a replacement, i.e. does it fix it gud for a long time or is it just temporary?

cheers!
