Recommendation for Potato Seeds Please

I'm a bit late out of the gates on this one, I know, but keen to get chitting!
What varieties would you recommend and who is your preferred supplier??

Probably:
- one salad type
- one really good roaster
- one all rounder

I have a Wyvale nearby and a Dobbies but last year I ordered online form Dobies.

Thanks!

Is that Wyvale in Nailsworth or around? There was also a large garden centre, can't recall the name just on the main road between Stroud and Gloucester and I used to buy a lot of good stuff there a few years back anyhow.
