not an awful lot then for 200 smackers
i priced it up, pump and pump filter about 100 quid
flow thingy (which i dont use anyways) 10 odd quid
fuse 3 quid from halfords
switch from halfords aswell
fittings and pipe about 10 quid
130 ish quid to build, i just used that way, as its built and "plug in and go" you dont need to faff around
