southeast MN lakes

[bcd]

The wife and I are going to take a short vacation at the end of July. It's just going to be us 2, so I'm thinking MN is a good option since you don't need a spotter. The twin cities are 5 hours from us, and I'd like to not drive farther than that, so anyone have recommendations for lakes. Here's what we're after:

southeast MN
good ski water (we're leaving on a Sunday and coming back around Wed, so weekend lake traffic shouldn't be an issue)
quiet lake, don't need a party cove
cabin on or near the water
slip for boat would be nice
