I see a lot of requests and trades for things really high level, and I've made a few of my own. It's hard to get some of those trackers, but there are low level trackers that can suit your needs just fine.
All of these are open sign-ups or you can get invites easily. Obviously these sites aren't as good as the high level ones but I think they're good enough to suit most people's needs. This list is from experience
Swebits can replace Swedvdr
Tv.torrents.ro can replace Bitmetv. (and thebox is really good)
Stmusic can replace what.cd and waffles
Cinematik can replace KG (it was open sign-ups until a few days ago)
Textbooktorrents, elbitz, and docs.torrents.ro, bitspyder, learnbits, and ebookvortex are good for e-learning and you can get them all easily. (but Bitme is A LOT better)
CZONE is moderately difficult to get, but it's a better tracker than almost all the foreign ones higher level than it
And Torrentleech in my opinion is just as good as SCT
Add your own.
