Ah, well there are tons of threads on inexpensive cables and wires, and a whole section to search on AudioAsylum too. It may help to list her system components if you are asking advice about wires, since it makes little sense to buy cables and wires that will not live up to their potential (not be worth the investment) given the system you are pairing them with.
Simply on the basis of bang-for-buck on the entry-level I'd look to the smaller independent manufacturers making solid products, such as DH Labs and Signal Cables, rather than go buying boutique wires where you are paying for their advertising budget and overhead.
