@FTM and
@Lupis thanks for your recommendations! I love a bit of a bargain so will order a bottle of the glengoyne legacy whilst on offer.
Its my birthday in January so will be sure to get a bottle of Glendronach 12
I don't think you'd be disappointed with the ones FTM mentioned, especially the GlenDronach 12 (the 15 and 18 are excellent, but a fair bit over £40!). I've not tried the Tamdhu 12 since they released it as part of their core range, but the 10 it replaced was a good whisky for the money so I'd expect that to be pretty good as well.
One final tip, if you do get the Legacy I'd advise you to leave the whisky to sit in the glass for at least 15 to 20 minutes before you start on it, to let it open up a bit. That's particularly important if it's the first glasses poured from a newly opened bottle. It can be interesting to nose and taste it as soon as you pour and then leave it for a while to compare, but if it's your very first experience of it I'd say just let it sit for a while before trying.
Hopefully you enjoy whichever ones you pick up anyway.
