Which arcane enchanter is closest to a fast travel point?

Solution 1:

I like to use the arcane enchanter in Drelas' Cottage. Its easy to fast travel to and has both an enchanter and alchemy station. The only draw back is that you do need to cross a loading boundary and that the owner is a rather high level mage that does not take kindly to strangers.

Here is the location on the map:

If you are playing Skyrim on steam, there is a nice mod in the workshop that adds a fast travel icon on the world map for every player owned house.

Solution 2:

The fastest one to travel to that I know of is in Mistveil Keep, in Riften. There is an arcane enchanter just inside, in the first room on the left.

Solution 3:

Perhaps not the fastest, but very convenient because it's very close to a marketplace and some player-owned storage containers, is the one in Honeyside after you've bought the upgrade.

The house is just a short walk from the entrance to Riften, and the Enchanter is just downstairs. If you're Thane of the Rift, you've also got your handy-dandy Housecarl, Iona, available if you need help carrying stuff. And, if you're also inclined to do some Alchemy, you can buy another upgrade for the house that puts an Alchemy Lab right in the next room.

Like I said, it may not be the absolute fastest but, I find it fairly convenient. It's the one I personally prefer to use.
