Never want to haul those buckets again? Love large, predatory fish but hate/fear the amount of maintenance needed? This is probably your best bet. Drip systems are excellent for water quality, and you can't beat the price or the efficiency that they offer.
Setting up a drip system is as simple as buying an adapter for your sink, hooking up a filter system (and an auto-doser or additional filtration, if you have chloramines in your water), and setting up an overflow for the waste water. Once they are set up they constantly change the water in your tank, ensuring that it is stable and crystal-clean. Here are a few resources to get you started:
Primary resources for setting up a Drip system (overflow or drill)
Neoprodigy's Drip system:

This is an overflow system, not a drilled system but he does show which auto-doser to use for putting prime or salt into the system evenly.

This is just a beginner's guide, step-by-step, on how to drill a tank. I believe it is geared towards glass tanks, but it is worth a look.
Pharoah's DIY Drip System: http://www.monsterfishkeepers.com/forums/showthread.php?t=201899
This is another good example of a drip system. It has a price list, but is not as in-depth (as far as discussion goes) as Neo's thread.

Danger Chicken's Automatic Water Change System: http://www.monsterfishkeepers.com/forums/showthread.php?t=152445
This thread is for an timer-operated DIY automatic water changer. This system is more complex, and more expensive, than what you would get with a more basic drip system. In my opinion, a system like this would have to be watched a lot more closely, and the sudden changes of water still hold the same shock value as regular water changes. It does, however, give a good price list and it is a feasible (albeit overcomplicated, in my opinion) alternative to the more popular and stable traditional drip system.
Chomper's Howto DIY Plumbing without angering your wife/landlord: http://www.monsterfishkeepers.com/forums/showthread.php?t=55152
This is a fairly detailed guide on how to run plumbing without devaluing your home (wife and landlord friendly). I haven't ever gotten into this style of plumbing, as I simply use coaxial-cable brackets to wall-mount the thin hoses, but it is a good read.

Simple Chloramine filter: http://www.thefilterguys.biz/chloramine_filters.htm
This is more expensive in the long run than setting up an auto-doser, and in my opinion it would be more of a headache. It is worth looking in to, but I personally wouldn't recommend it.

This thread gives a nice look at what a more complex system might look like. Not my style, but might be worth it in some cases.

Just some good discussion and extra info here.
