Yes. I'm not willing to drop $200 on a plastic Main Street Station and another $100 or so at least on the MK train. I just don't have the room. I used to have the astro orbiter and dumbo spinners. Bought them broken for cheap. Took them apart and replaced the gear. Then sold them on for enough to buy the GF. The spinners didn't do much for me and they have completely the wrong scale, though everything is kind of the wrong scale. I had a shot at a Haunted Mansion and probably should have bought it, but it's based off the DL Haunted Mansion and I just didn't want to spend the money they wanted. The one piece I want and am likely to get is the Sorcerer's Hat. I just haven't seen one I'm willing to pay for yet. Then I would have the symbol for all 4 parks, even if DHS has since gone away from having a centerpiece symbol.
Really though, it's the TTC piece that makes it work. Without that, you are stuck with just lousy ovals. That being said, there is now a guy making switches on EBAY. Not the TTC piece, but his own manual switch. $100. Probably well worth it just to make better layouts since the TTC is hard to find and stupidly expensive when you do.
