My mate was looking for a new guitar and I was doing a bit of the e-legwork for him. Thomann's had a good price on the guitar he wanted, so I looked at some reviews. Some complaints, as you'd expect for any international online trader, but also lots of positives.
One of the reviewers, though, suggested that prospective buyers get in touch with dv247 here in the UK and ask them for their Europe-wide price match. My mate phoned them and got the deal, so his guitar didn't need to be imported, cost the same, and will be more easily returnable should things go wrong.
Other UK online retailers offer a Europe-wide price match, though I can't for the life of me remember which ones.
EDIT: you'd still be at the mercy of the couriers, though...
