thing is with internals you never knowhow long they will take , things in the way dirt on the floor ,"could you clean that please"
dont forget the possible damage to internal stuff the od pc mouse not working any more due to possible water damage
just a nightmare! also if the internal clean is quite disruptive they might ask you to skip next time cleans
i find regular internals unreliable
at £145 it would have to be like 6.30am start or latest 7am for me that way we will be packed and ready to go on to domestic
i think that would be the minuim price wouldnt go any lower considering the frequency
