You didn't indicate if you plan to race or not. If you plan to race, buy the 250F or you won't stand a chance. If your not going to race, the new CR should be a big improvement over you 99. There is plenty of hop up potential if your not tied down to displacement issues. It will probably take you longer to get bored with the 250F than the 125. The 250F will be a LOT harder to work on :bang: , and cost a LOT more in the long run :( . The 250F has a LOT more bottom end, a lot longer power band :nod: . The 125 probably has more grin factor :laugh: . You didn't indicate your size either. If you are on the small side, the 125 should be a good pick since your just beginning, if your medium to big look at the 250F. If your not racing, you may even want to look a 250 2-stroke, while it may be intimidating at first, at the rate your practicing you will quickly adapt, and you won't get bored.
Not sure, but I just may have confused you even more. :think:
