I'll certainly check in store before I buy anything. I've got an Ikea desk right now, and it's fine, strength-wise, but the top is cheap laminated fibreboard and easily scratched. Scratches tend to swell if they get damp (from cups of coffee, etc.).

I'm fairly sure that my previous company uses these desks or something very similar. They're pretty good, but the cables drop behind the privacy panel, which is fine in an office where they're back-to-back, but might be a challenge in my (smallish) study.
