I have only just got my ED80 and I a just blown away with the quality of this scope. Having just gone through the process of trying to select one i know the confusing amount of choice when it comes to brands, doublet, triplet etc. In the end I bought an Explore scientific from here in the for sale section. At the time I had never even heard of this brand but after some research I came to realise that it was a good choice with a very high standard. Different models come with many different choices in accessories etc. The Synta brands.. Skywatcher, orion etc are all very simular but all still good. There are also some arguments about quality of focusers etc. One word of advice. In all cases if your choice is to take photos invest in a decent field flattener or your pics will look like your warping out on the enterprise. I hope this helps.
