Hi Adrain,
I'm looking at getting the 4.5mm in the Explore Scientific 82 deg. Thinking hard about it and scratching my head lots over it. Have you got one to share your thoughts?
At such high power, it won't be an ep that will get lots of use, so I think I can handle some defiencies (maybe

, that's why I'm still thinking

).
They were about a $100 off on sale a couple of weeks ago, so I hope I haven't missed out by the time I make up my mind.
In general, from the plenty that I've read, people seem to be quite happy with the Explore Scientific range which is why I'm considering it myself.
