The only better groups that I'd consider would be Sora/Tiagra. 105 sells itself as entry level racing, which I don't need since I have another rig for that. Tiagra seems more mid-range between the two and harder to find thus nearly as expensive. Sora seems good but still having trouble finding it from any reputable site & reasonable shipping. I'm going to order the Claris next week and post some feedback on it.
