I would have to agree about the second broodmare.
Her offspring look fantastic and she is a lot cheaper than the mare one as well.
In my opinion I believe mare two should be the price of mare one and mare one the price of the second mare.
Mare two is deffo worth a look if you are thinking of buying.
If I had the means and money I would be taking a look myself as I just really like the look of her to be honest.

I'd definately go for mare two. Always a bit suspicious of mares 'put in foal due to lack of rider' in my experiance it means that they aren't a very nice ride so can't be sold as much for riding.
I'd say the second proven progeny... for some reason I think i've seen he first horse before (not with the person thats selling it) but somewhere else but maybe wrong.
Out of interest what sort of broodmare do you want and what type of foal do you want to breed, what stallions do you like?? (I'm sucha nosey person!!)
