I'm not sure if they still had the RX last year (they don't now for sure), but it was a slightly beefed up EX that should be cheap if they still made it. The Ride EX is also a pretty good do-it-all bindings if you like aluminum. Not gonna lie, they're a no frills option, but they've worked well so far for me.
Otherwise, some K2 Indy's or possibly Formulas/Auto Uprises at some places should do the trick. The Formulas and Auto Uprises should just squeeze into your budget if they have them from last year.
Might want to make sure you take your girlfriend's bindings boots in to make sure they'll fit well with male bindings. There probably shouldn't be much (if almost any) difference, but it's always better to make sure.
