I Agree!! look into Zenterra also, after going through this thread. At first my ID recommend their electrician, which quoted me quite high. Then, I proceed to source for another 2 quotes, one of which is Zenterra. Why I like about them. For a start, if you get your lightings from them, they provide free installation!! how's that? (other electrician charges $7~$10 per installation, so I estimated I save additional $300 from that alone). Moreover, their lightings are all reasonably price, that even my ID also say that we got a good deal. Their lighting selections are also quite good range. I manage to get all my lights and ceiling fan from them, and they give further discounts of 10% (i think it's 10%). Their electricians also very accomodating to changes request, even last minute additions. And their wiring standards are reasonably ok. More over, they do not chase for payment. By the time they send me the last invoice, I also paiseh for delaying payment for so long. Do check them out.
