That 2" does make a world of difference.
Also, the AccuFeed system leaves a traditional walking [even feed] foot in the dust.
I noticed that the Skyline doesn't have a true extension table available even as an optional accessory.

If I had the budget to choose between a Skyline and an 8200 I'd be inclined to go with the 8200. It doesn't come with an extension table, but the "extra wide table/clothsetter" can be purchased separately. (be prepared for some serious sticker shock, though. LOL)

i don't think you'd be unhappy with a skyline. i only suspect you'd be happier with the 8200 over the long haul.

Have you considered the MC6600P? It should be priced somewhere between the skyline and the 8200.
9" to the right; accufeed system (although not as much a joy as the newer accufeed system found on the 8200 and ups); extension table comes in the box; an absolute workhorse.

check out the 8900 while you're at it.
higher in price but all but two "must have" quilting feet accessories come in the box.
i've had mine for two years. the only two things i [personally] had to have, so purchased separately, were the quarter-inch and the open toe accufeet.

i fall in line with those who encourage you to take some fabrics to sit down and test drive anything you are considering. make sure to take along a small quilt sandwich, too, so you can compare the performance for quilting - not just for piecing.
