Hi again,
Have any of you guys had any experience (or any opinions) on the siebert barlows

I am particularly interested in the modular range (scroll down to ad#3, product G). They claim to be on a par (if not better, they use more glass) with TV. I just read on CN that 1 guy reckons its the best barlow he has ever used. If they are as good as they say they are, this delivers huge diversity for $249US. Essentially you get a 1.5x, 2x, 2.5x,3x and a 3.5x barlow which will just about cover all focal lengths with just a couple of EPs. (1 even!!!!!!!) I know some people feel that it is a PITA to change barlows etc but this really doesnt bother me. Of course, I would prefer to have premium EPs in every focal length but until I win lotto, $249 seems interesting. They have some pretty impressive specs on their website. I am interested in what observers more experienced than myself think about this.
