Keep doing your research and reading up on kegging. If you get into brewing regularly (and larger batches) it is certainly the way to go. Its a lot less cleaning for sure. You actually could even keep brewing 10 L batches and still keg - you'd just buy smaller kegs. You may not find it as feasible though as increasing batch sizes and kegging 20 L... - Both are possible. I have seen 10 L kegs on the web but you'd have to wait for delivery etc...
Good luck!
