If you like the Laphroaigs then either Cask Strength 10yr or Lore are very good offerings.
Kilchoman is definitely worth a go, not quite as peaty as the above but a nice smokey profile and they do some very interesting bottlings.
Ledaig I agree has a bit of je ne sais quois, some really nice earthy funk. Got a bottle of this on the go at the moment which is very nice

Yeah can be had at a good price. In my experience a much more 'vegetal' peat rather than the big smokey hits you get from Laphroaig, Lagavulin etc. Worth a go, but quite different.
