Hi,
Great razor, but no matter how much you strop it, it will need honing first. I'd get it done rather than doing it yourself. It'll be done right & give you a benchmark for how it's meant to be, & it'll save you having to buy stones for a while.
I have a Jemico, though it's the one with the padded leather handle & it's very good. I can't compare it to a Miller, but that's a fantastic price (especially by U.K. standards).
As for the strop conditioner, if you're like me, you may need it after you've had to sand the nicks out of the strop while learning, but it's not really essential. I've used hand cream with good results.
It's great to master, so take it easy & persevere!
