Chris, thanks for your input.

Good. Juniper probably ensure at least 300k routes, with other features
turned on.

Good again and for half price of a green C7201 ;-)

I rarely use GUI. On Cisco they produce loads of useless lines. I am a big
fan of CLI since my first Linux box. However, that's more in case someone
less skilled has to take it and add a firewall rule in case I am off few
days or whenever my plane would crash, until they change them.

I've seen JunOS generates nice OpenBGPd-like configuration files. I am
familiar with HP cli and Foundry CLI. I've also heard that JunOS is way
different than Cisco but that once you get used to the synthax, you don't
want to get back on Cisco one.

However, that is no big risk. They seem to be a nice option at all levels:
price, performances and features. I am just not sure to buy the DRAM from
Juniper, 800$ for one extra GB is a bit expensive.
