I like dimple 15 but for the same money I prefer Glenlivet 12
if you want to start, minimum spend on a drinkable whiskey is ~$50
for a beginners scotch @ $50 you can usually get glenlivet 12, glenfiddich 12, dimple 15, balantynes 12, or chivas regal 12 - any of these are very approachable drams
If you are happy to spend the coin I would say the best one to start on would be Glenmorangie 10 year which will run you about $65
best value would be JW black for $38 @ dan's but this is a) not as nice as the above b) much peatier, which is not as beginner friendly
