Yes, "through experience to excellence"...and then You die ;)

You can always position 1800 as a start-up solution, but with clearly
drawn borders - "this box will do that that and that and should not
exceed it's vendor claims. Anything else - it's Your call".

First You can see it on some presentations. Secondly, there's Q&A on
CCO:

http://www.cisco.com/en/US/products/ps5853/products_qanda_item0900aecd80181208.shtml

...and it says:

"Q. What is the performance of the 1800 series?
  A. The 1800 series of integrated service routers have been designed to
  deliver multiple concurrent services at wire-speed performance-up to
  single T1/E1/xDSL speeds. [...]"

Secondly, there's router performance chart - sort of reference summary
table for various platforms with performance in kpps
(fast-switching/CEF) here:

  http://www.cisco.com/warp/public/765/tools/quickreference/

Please bear in mind there are situation where traffic or first packets
will be not CEF-switched and thus for real-life scenarios figures will
be lower.

And thirdly, there's google, with people like me (in my previous life)
sharing some info from time to time (sorry for tinyurl but that was
very long):
