you'r not F'ed at all! the superslim has a nice design and you can use your un-jailbroken console for online gaming! there are alot of good deals on the PSN. i can even recommend subscribing to PSN+
You have 2 options:
Buy an older PS3 from wherever you do that (gamestop, ebay +++)
use the money on games instead of a new PS3. and keep playing online!
i recommend going with option 2
