Aldi were doing Glenrothes Select Reserve recently, local one still has a few bottles left. Light, smooth, no smoke.
Auchentoshan also turns up on the cheap shelf from time to time, Triple distilled which really smooths it off.
On a trip to Oban, I visited the distillery and picked up a bottle and it was lovely. Never seen it anywhere else, but worth looking for. Very lightly smoked, a hint of salt, but without phenolic overtones of the islands
Also worth checking out is Glenmorangie Quinta Ruban – Glenmorangie which spends some time in port casks which gives it a sweet, chocolatey finish.
