There are many underated titles that still go for good value if you don't want to spend 10k.
You'd have to look harder now, but at the start of the year you could still buy good Williams machines that have been restored and shopped for 5k and under. You could have say a Whilrwind and a Hurricane for your 10k.
Haven't seen much come up lately but i got a very nice video documented restored Cyclone off the facebook page this year for $4,200.
