I bought Polk RTi8's at Circuit City and love them. I suspect they sound very similar to the Axiom M60's because they sound very similar to my M22's only they have more bass. They sound a little more detailed to me also, but I have been having trouble with my M22 secondary system(different room, receiver issues) so I would not take that comment as the gospel. The Circuit City near me does not carry the Polk LSi line but their website has a "dealer locator" that may be some help. Overall, though (and I know this is no help at all) you are looking at 3 outstanding options and will end up with a great sysytem no matter what you choose - it's just a matter of sound preference/price/appearance.
