I have a Janome QC 5250 that's an amazing workhorse. It has some extra stitches but I don't use them much. The ability to move the needle from extreme left to right ensures I can adjust the 1/4" perfectly. It does not have a built in walking foot but I use an after market one. I like the flexibility that if I don't want to use the walking foot that I can take it completely off. It's an electronic machine but not a 'computerized' machine. Sorry, no thread cutter or bobbin alarm, but you can see the bobbin because it's under a clear top plate.
I have the Horizon too, but with it's computerized brain, it refuses when I ask it to go through too thick seams. Go figure! The QC also has the extension table and tons to special feet that store "on board." For a $1000 budget, you can get a nice Janome machine.
