o they dont have paying version anymore
If you want the "paid" version, all you have to do is buy something from the MannCo store and you get all the non-item perks (expanded backpack, ability to send gifts, etc).
I
believe that if you want say, the proof of purchase, and possibly the medals (though I don't think they were being given out) you'll need to buy a gift pass off someone that still has one. Most people selling games aren't going to have these, only people who bought TF2, then bought Orange Box, and never redeemed the gift will still have it (and I'm not even sure if it will work, and I'm not even sure if you'll be awarded the proof of purchase or anything for it).
If a gift code does still award the proof of purchase, expect to pay a premium for those gift passes because if any do exist, they're going to be rare... and apparently some people like to wear the proof of purchase so they can say dumb shit like "fuckin' f2p noobs".
