I'd go with a Fluval FX5 or a Rena XP4. Both should be good for your size tank. Look on ebay, just look at reliable sellers, but as long as it comes new in the box, it should be good. (You might even be able to find a used one that you can clean out thoroughly, though I would avoid ebay on that one and look at local options so you can see the state of the filter first. Remember, though, that initially to replace ALL of the media, it will run around $25-50. The new ones come with some media, not all that you need though.)
As opposed to making a land side, which can be a pain, you can work on making an above tank basking area. These are good because then you can use all of the actual tank for water and the above area for basking. Since you have a female, you can build in a nesting area too for her future eggs.
You don't have to go with a MVB, you can use your two lights for as long as you care to, and then if you want to upgrade, you can do that whenever.
For a 100 gallon tank, you may need 2 water heaters, but those are pretty cheap.
Oh, and the better filter you have, the less water you'll need to change out, which helps a lot. Also, your turtle's water doesn't have to be awesome water, if your drinking water costs a lot and you have well water available (for like showering), that might be fine for your turtle tank. Depending on the filter you buy, a lot of them will remove a lot of stuff from the water, so that can help out.
