I play with a Samsara and absolutely love it. It is the best hitting cue I've ever used. This isn't just my opinion. Every time I let someone hit balls with my cue they tell me it is unbelievable and that I'm cheating.
I believe they all hit very similar and that any differences would be based on the shaft you use. But regardless of price they are all super solid.
As for shafts, I currently use the Predator 314-2. I have a Tru-Shaft as well but just haven't made the switch yet. It is a little thicker taper than I'm used to and I know I'd have to adjust, and haven't wanted to go through that yet. But I do like the Tru-Shaft and think I will be switching soon.
I believe Danny Smith uses a Samsara with a Tru-Shaft and loves the hit as well.
I think it's worth mentioning that I have heard NO ONE say one negative thing about the Samsara. Everyone thinks they're good cues. They might prefer another cue, but that's a matter of taste, not a criticism of Samsara.
I get my equipment from Mike Fieldhammer who helps with their website and inventory. His number is 612-802-0519. He can answer questions on availability, pricing, and is a knowledgeable pool player so can speak to different hits. Most importantly he's good to deal with, so as long as he knows you're not kicking tires he might let you order something with a return policy if you're not thrilled with it. He's looking for happy Samsara representatives, not a quick scalp. If you give him a shot I'd bet you become one. Tell him Tin Man (aka Demetrius Jelatis) says hi.
