Aw, cmon. You guys don't like 4-ways? I mean, I wouldn't run my uncut Auroras in a demo derby, but I'm actually thinking about putting a stretched 2-lane figure 8 with a 4-way (Tyco track) on a door and running some beaters on it with the kids just for $4!+$ and giggles... But I do agree that the layout in the auction is nothin' special but pretty pictures. Gotta give the guy credit for good marketing, but it'd stink to get this thing home and find out how much fun it's not...
Hey Boss (and anyone else into Faller), I had a 4x8 layout made of Faller track as a kid. I liked it. I was in an old hobby store putzing around, and I asked the old guy what he wanted for this cool old track with the curbs and center lines, and he filled a huge bag with most of what he had left and gave it to me for $5.00. Before you get excited, it wasn't much variety... all 31cm and 54cm curves and mostly 10cm straights, with a few lane-change tracks and overpass supports and other odd parts thrown in for good measure. So I built a layout with it... yes, it was like having a whole layout of 6" straights, it clicked a lot. I was in junior high, what did I know? I still have a box of track with a few of the original boxes; I traded most of the odd non-track parts to a guy in New Zealand for a couple of Faller Mercedes bodies. (And the dang wheelbase and screwposts aren't even close to Tjets!

Had to cut a chassis to get it to fit...)
Anyway, are you talking about Faller track that connects with model railroad type brass clips? That's what mine was, and the clips happen to interchange with the Atlas/Lionel track I use now, so they came in handy. I like that connection system very much... smooth joints and good electrical contact. If you can get lots of that track cheap, I say go for it. The only thing is that the track has those little raised ribbed traction strips just outboard of the rails, which are good for Tjets I guess, but probably not optimal for magnet cars. I ran Magna-Tractions and eventually 440s on it okay, though, so maybe it's not a big deal...
Funny, I never ran Tjets on mine, since I didn't have Tjets as a kid. I've been meaning to set some up and see how it does...
