Highest price
Sobre: I have read the above post and replies and of course, I have arrived at a slightly different answer. The amount you should spend is just under the limit it would take for your wife or significant other to re-read your life insurance policy to be sure that they would still eligible to collect after rendering their judgement on your spending $$$$$$ on your bike.
There is a relationship of diminished weight of the bike, the rider, ambient conditions, physical conditions and inherent athletic ability and your ability to climb. My advice, Spend what you can afford with a clear conscience, and ride to have fun. There are times when chasing extreme personal bests can leave you financially in the hole, Physically burnt out and possibly paying alimony! Have fun and it sounds like you made a heck of a deal on your last bike!
