Very good advice!
It's also a common recommendation we give to newbies to try and get to a local viewing night at an astronomy club or star party BEFORE buying a telescope, to actually LOOK THROUGH the different types of telescopes before you buy them, see how big they are and whether you'll be able to transport them easily, etc.
Some people might also feel that astronomy is not the hobby for them after standing outside in the cold with the mozzies, being frustrated by clouds etc
MyAstroShop also sells the Skywatcher dobs at a very good price.
