Thanks to all. I was leaning towards the Varizone because my brother-in-law has the Truglo version and it is one heavy awkward lookingscope. Plus the tube is so short it wouldn't fit on the Excal's rail with the supplied split rings and I would have to use high mounts. Since asking this question I have been able to hold and compare both the Lumizone & Truglo and my opinion is that the Lumizone islighter and appears to be the scope for me. It also appears to be a little clearer in optics and has less crosshairs to get confused with.It is still bulky looking in the back where the battery goes but being a longer tube makes it look less bulky than the Truglo. My brother-in-law likes the Truglo better so I guess to each his own. Thanks again.
