Why will it cost more to operate a cheap one?

Very nice people at buckeye's. I just met the owner at the Cincy frag swap a couple weeks ago. If you don't want to do online buying. Rod can hook you up for a reasonable price and answer most questions. http://www.rods-reef.com/general.php

Unless you get one with odd size filters, aren't the filters interchangeable? So, if your filters don't perform just change them out for better ones?

The ones on Ebay generally use membranes that are rated at higher pressures than better models. In Oak Lawn you have lower pressure water feed (40 or so PSI). So in order to produce the amount of water, more waste water passes through the RO unit. So that $69-99 price tag on ebay adds an extra $20-40 to your yearly water bill.

Stages refer to the number of steps that the water goes through during the filtration process. This depends on the particular unit and is usually determined by the condition of the water going in.
Being from Oak Lawn, I'd say you shouldn't need more than a 4 Stage RO/DI for your water. That's 2x Prefilters, 1x Membrane (3 stages) and a DI stage (stage 4). You can get a 5 stage (3 prefilters, 1 Membrane, 1 DI stage) if you wish that will reduce the amount of prefilter changing you need to do.
Now, me personally, I used a 5 stage RO unit (When I was living in Burbank) and didn't bother with a DI stage as the water coming out of the unit was clean enough for my tanks w/o the DI.
