I'm lucky their shop is only half an hours drive from me in Huntly.
I've had several bottles from them and all have been equal to if not better than some of OB's from the distilleries themselves.
Two I've had this month are a 14yo Aberlour, very nice, and a 13yo Highland Park. Both around the £23 mark.
The WG Highland Park just beats the OB Highland Park for me, must be because it's not chill filtered, it just gives it that extra something.
Their prices are resonable as well, haven't tried any of the more expensive bottles yet, but will treat myself some day.
Highly recommended if you can get your hands on a bottle.
