If pricing is a concern that shouldn't rule out a VPS. Managed seedboxes are way more expensive than setting it up yourself for the same amount of storage/bandwidth.

Go to lowendbox.com and/or use serverhunter.com to find a VPS that's more in your price range. I currently pay $22/mo for 8TB of storage and 50 TB of bandwidth at 1Gbps.

If you absolutely don't want to use a VPS for some reason, then I had a very good experience with feralhosting. I used them for 3 years without issue. But 8TB with them is around $75/mo compared to the $22/mo I'm paying now.

whatbox.ca has been good to me too. They expanded my storage for free during a server upgrade, which was very nice of them.

Been with https://www.seedhost.eu/ for a while. They're very competitive and everything works as you would expect.

Pulsedmedia has some decently priced offerings. I've used them a few times here and there. Pretty solid. You can probably find something to your liking in the neighborhood of 9 to 10 bucks a month.

If you have a Raspberry Pi or an old laptop you could install a torrent client and vpn and host it that way. If you want it hosted, I used ultra.cc for a short time and it worked great. They cost €5 ($5.21 USD)

So, I used to have my own VPS

Not sure if this is a requirement for you but if you are used to using your own VPS then you might be used to have root / SSH access. When browsing seedbox services you may want to double-check if their plan(s) offer that.

I mean a VPS is ideal, let's be real. lol
