I am using a an ML, with ~2500 hours of play over two years (evaluating a large LP, very clean collection). Playing Relayer, by YES, this morning - great sound.
As cartridges go, the Hana line-up is VERY well vetted. I expect the reason dealers do not demo ALL of the Hana line is that Hana carts reputations are so solid - would you really need a demo if you were buying a Ford F-150 pick up?
IMO - as long as the cart complies with your tonearm and phono preamp specs, give it a try. Learn from experience and get comfortable with the fact that carts are semi-consumable components.
If it helps, Hana has a great return policy (2 years for manufacturing defects) as well as a generous trade-in policy. I have no affiliation, and I have a Hana Red in the box just waiting for installation...
The good news is there are LOTS of great carts out there to try.
Good luck...
