The M10i is perfectly capable of handling the full table and then some. 
The only question is whether you want to buy more just in case your needs 

That said- Last time I spoke to a Juniper rep I was told that their 4 port 
GigE card for the M7/M10 is oversubscribed 4:1- ie the backplane 
connection is only gigabit. Check into that if it is important to you. I 
may have been misled or things may have changed- frankly I didn't look 
into it much as an equivalent Cisco solution with additional ports came in 
at 1/4 of the price :(

The pricing for all of this stuff is so ludicrously flexible it isn't 
funny. If the company wants you as a client (for marketing reasons or 
whatever) then suddenly a $50k router becomes a $25k (or less) router. If 
you point out a competitors router is xyz dollars less you may suddenly 
find yourself with yet another discount. Get quotes from everyone, compare 
features, and don't hesitate to push for better pricing from everyone.
