i also in NS, that's why i can only afford a 2nd hand NSEW 1/3 hp chiller. If you get a brand new cl450, might as well spend another $200-$300 more and get a 2nd hand RR, teco or pacific coo chiller. it will serve u well in long term. Currently my tank have 1 eheim1260, 1 eheim1250, 1 atman104, 1 resun md55, 2 seio820, 2xt5 lightings, 1 250watt MH and the chiller is working very hard. Therefore u might wanna consider a more powerful chiller when it comes to long term, say u decide to upgrade lightings or something. .
