As I have been involved in purchasing and supply for many years, I can tell you that
there is no substitute for shopping around! Never show your hand until the last minute, and even then be reluctant.
Sometimes it can pay to cut out the middle man and go straight to the manufacturer. However, you are only buying once off. the salesman will know this and charge you accordingly. A distributor will sometimes get the product for a lot less, as they buy from the manufacturer on a regular basis. So even after overheads and GST have been factored in, you often still get a better deal at the consumer end.
Notice the quantities a corner store will order cartons of coke, and woolies orders pallet loads. the price difference is way in favour of woolies.
In some instances, this can go the other way though, when you look at the overheads on a brand name and supplier.
I resist the urge to slap telescope shop assistants every time I am browsing and hear them bull**** a customer. They watch your body language, ask you lots of questions to pre-qualify you like what do you do for a living, are you married? got kids? etc. Then they will try to chat you up and establish common ground with you. After that there is the salesman you have to judge is being truly genuine and helpful, or trying to help so much you feel like a prick if you dont buy.
Make sure you look through some telescopes at night with someone who is into the hobby before you seriously consider parting with hard earned cash.
If you buy a peice of crap you will be stuck with it. Second hand telescopes are hard to sell and you will ususlly lose lots.
Again.....
there is no substitute for shopping around.
Hope this helps..
