I would go for either the Beko or White Knight condensers in light of the recall on Hotpoint and Indesit dryers http://safety.hotpoint.eu/. In time existing dealer stock will be modified or replaced as decided by the retailer. Good stock of dryers should have a green sticker on the rear alongside the model details label.
If you have provision to vent I would go for a vented model any
day, again the White Knight is always a good bet.
