HP Probooks and Lenovo ThinkPads aren't bad quality - I usually recommend the HP ProBooks or Elitebooks with an i5 and likewise for the ThinkPads - usually the disk write speeds in them are pretty good too, but there's always the SSD route for Management staff (if they're that tech savvy!). Lenovo's are a bit more budget-friendly whereas you're looking at around £490+ for a nice performance ProBook/ EliteBook.
