I have both a Vortex Spitfire and SPARC II....both were at the less than $200 price point... I have a rather bad astigmatism, and the ability to focus the Spitfire due to the etched prism was a selling point... I don't particularly like the multiple concentric circles and would like a larger center dot... the red dot SPARC is currently on the PCC as the dot is fairly spherical (unlike other dot sights) when looking through my distant lens portion of my bifocals...it replaces my 1.5x16 ACOG, that with the slight magnification was a little slow in transitions.... poppers and not so much paper targets...after Area 6 Multigun in two weeks, will get back to working with the PCC
