They have a 737-200 sim, contact them and they will give you a contact of someone at Sim Tech, who will sort you out. One word of warning, they will probably tell you that you need 4hrs etc... I personally think this is a little over kill at 250Euro's an hour. couple of hours should be sufficent unless yo are really struggling.
Also check your PM.
