The Dovo's are a fine razor, but if you are going to get one, why not get one from Straight razor designs? It will come shave ready that way. I bought my first Dovo (and first cutthroat) from a razor shop, and it just had the factory edge. It could have been a bit sharper, but I didn't know that at the time, and as such, my first experiences suffered.
The other alternative, is of course, to find somone nearby you who can hone. we have members who live in the UK (I assume you live there as you quote in pounds) that can do a fine job of honing. Maybe one will pop in here and offer their services.
That trad kit you link to will get you off to a nice start. The strop will be on the narrow side I think, but many of us start off with the narrower strops (and many prefer them), but some of us go for wider later on.
No use dwelling on the razor that was sold...It's gone.
