My dd used Larson's Math in early elementary. It is a decent math program but not to be compared with EPGY. Larson's Math is good for the visual learner and has an easy interface. I wouldn't say that it is geared for the gifted learner though if I remember correctly the student can progress at his/her own pace. Also, it only goes through pre-algebra. My dd9 enjoyed Larson's Math when she was younger, but she likes ALEKS better. ALEKS is another low-cost option.
