If you go to a reputable salon (and not a hole-in-the-wall storefront), then acrylics and gels usually run in the same price range. In my area, that means about $55-65 for an acrylic full set and $65-75 for a gel full set.
Gels are less damaging to your natural nail, but take little bit longer to do. Acrylics can usually be done a little quicker than gels, but can cause weakening of the natural nail. Most salons who have nail techs worth their salt can do an acrylic full set in about an hour or sometimes less (pink and white/forever french), and gels in maybe an hour to an hour and fifteen mins (sometimes less).
Fill-ins with each probably take about the same amount of time. When you get pink and whites/forever french, fill-ins can sometimes be a tiny bit more involved. Assuming you would go about every two weeks to keep them up, then your first fill in would be just filling in the pink portion at the bottom of the nail. Then your second fill in would involve filling in the white AND pink portion, and this process would alternate every two weeks or so.
If it were my choice, I would go with gels. But either way MAKE SURE YOU GO TO A REPUTABLE SALON/SPA! It will cost a bit more than the store fronts that seem to pop up on every corner (at least around here), but a reputable place that values safety, sanitation, customer service, and quality products is worth the extra cost.
Good luck in your search!
