it's definitely cheaper to make one, unless you can find a used one somewhere for a good price.
i also think it's better to make one, because then you can make it to your exact specs, instead of having to purchase a skimmer that will fit.
i'd rather purchase the skimmer i want, and then make a sump to fit it.
the larger the footprint the better. you will want plenty of room too keep equipment and possibly a refugium. i suggest a 30, or 40 breeder style tank. those have a nice footprint.
you can make partitions in the tank with glass, or plexi/acrylic sheets cut to size. i actually used cut down plastic cutting boards from walmart. that was the cheapest thing i found.
you need to decide what will be in your sump before you make it. will you keep a skimmer in it? will you keep a refugium in it as well? how about an auto top-off? will you have one of these, or will you be topping off daily by hand?
Mr. X, you think you could make me a list of things I would need and how you would sit it up? I have no experience with sumps or a refuge.
