What do you mean look like shit? Design wise? Not your taste? Beaten from use? Nothing lasts forever. Elaborate.
I already said why the ebay seats suck in my post above. They're flimsy and weak. For example, trying to get something out of your pocket while in a bucket seat, a cheap seat will flex really bad no matter how well it is bolted in place, a good seat may still flex a little but, but it is nowhere near as bad. And this is just from you leaning back on the seat. Imagine any kind of impact or higher load.
If you're doing track days, just suck it up and spend the money on a decent seat. It's definitely worth it for a car that will see the track. There are some cheaper decent seats out there as well, like sparco and other companies have steel framed seats, they aren't that light, but they're still about 60lbs less than a stock seat and some people don't like the way they fit, but that's up to you.
I would go and find a place that sells seats and go sit in them, finding an awesome and comfortable seat that you have sat in will make you more willing to spend the money rather than getting a cheap seat and then trying to pawn it off on someone when you realize you want something better.
And I'm not a fan of those corbeau seats at all. They seem to fit weird, they're heavy and ugly. But that's just my opinion.
