10 mil would be a fair amount for a MN
10 Million for a node and increased rewards for master nodes would be the way to go.

Crap I only half a million and I am not at home to be able to login to the exchanges for another 3 days to stock up on some. Please don't make any decision yet till I can get home and buy some at a cheaper price lol.

Don't worry you'll have oportunity to buy cheap
they don't decide yet if it will be 10 millions for a MN, the big holders want 30 millions to 50 millions for a MN! and the others like you and me find that 10 millions is enough for a MN! but you know like in every field in the world, the big holders decide. and the others are here just to ask funny questions!
Well from my point of view, a big amount for a MN is good for espers coin value on the first hand. On the other hand, the big holders,which are investors (the majorit of then, there are some miners too) can run easly some MN, look here:
http://espv2.miningalts.com/richlist, the top50 wallets have > 100 million coins. At 10 mill MN they will be forced to run 10+ MN (not a problem! you'll say...) but you must run them from diffrent IPs, that's the thing... Anyway the low amount holders will get 25% intrest staking their coins. (wich is way better then all other coins MN rewards). Or you can mine/buy more and run a MN.
