Playable? Are you freaking insane? Sentech + FPS is NOT playable. I would rather play with a freaking 28.8k modem online than Sentech's offering!
In any case, the REASON why most people install ADSL is because a leased line is too freaking expensive!
Gohan, it wouldnt matter if your administrator upgraded the leased line to 512k, because if their bandwidth managing software (assuming they even have that) is up to ****, it means that the other folks would hog the extra bandwidth anyway.
Before you pay anything extra, find out what type of bandwidth management software they run to make sure everything is divided equally and everyone gets an even portion of the line.
Because if they have bandwidth management software, it means they can in fact allocate more bandwidth towards your flat and then charge you extra for it (on your request).
Being capped does not nessacarily mean you're screwed. You can either take the expensive option and buy another account. Or you could look at services like
www.nukecap.co.za which offers a local proxy server you could peer to to get to international sites.
a Proxy server (locally) means you can browse international sites at decent speeds, and not have it crawl and time out like it currently does when you are capped. Obviously they charge an extra fee each month.
I am sure if you go through the previous discussions on the ADSL related threads, you'll see how much gig you should expect to use up in a month doing normal surfing and gameplay.
You should seriously have a sit-down with the administrator and let him explain the setup to you. Make notes, cause even if you don't understand, you can come here and explain the whole setup, and we'll try and give you the best advice we can.
Good luck
