Nope that is not my view at all. I can guarantee you one thing, if you go around the sales without a catalogue and just look at the horses, you will pick out maybe 10, 20, 30, 40 horses.....whatever. I bet if you go in to buy them you will be disappointed if you have 5k in your pocket. 25k just gives you more options. Fair dues to those that end up with the nice one for 5k but having the extra few bob always helps you get the one you really want. I only use 25k because that is my level and I would consider myself in the middle tier of owners who could never afford one for 50k but yet wouldn't drop to 5k or 10k because my view is that the biggest expense is the money you put in training the beast for the next four years, you better at least think you have a good 'un.
And I wouldn't be against dropping the prizemoney at the top either.
