Ubuntu Laptop

Now I am in the choice of a laptop for work (web development).

In this regard, the question is, on which laptop within 50k WITHOUT HEMORIUM gets ubuntu and works censibly?

I already had the experience of setting up Ubunt, but I could not start the sound card (X-Fi), so I want to avoid unnecessary haemorrhoids when buying a laptop.

ps Macbooks do not offer, disappointed in them.
