How is Charleston Southern University?

We’re considering putting this college on our list. My son is interested in computer science. Seems like they have some good opportunities? I’m really trying to find some Christian colleges with a more affordable net price as a financial safety. Would like to have a net price of under $20K/year (after student loans, so $25K is ok). This school seems like it offers generous merit aid even for average stat (B+) kids. We definitely won’t qualify for any need-based aid. My son’s stats are around a 3.4 GPA and guessing @ 1210 SAT.
Looking for affordable (Evangelical) Christian colleges if possible.
Is this school alright? Average? Decent academics? It’s not ranked, as other schools we are considering are, but worried those schools might be higher than we’d be able to easily afford. Any other similar options with a decent comp sci major?
Thanks!
