Trying to get a decent bulk colour printer for our arts/admin area

Estimate of use 2500 colour + 2900 b/w per month

Quote 1 - a 5 yr lease £400 per month inclusive of prints for a Ricoh 820DN

Quote 2 - Pay only for toners at £600 per set with a min of 2 sets per year for a kyocera taskalpha 300 with a colour set doing 12,000 copies and a black 20,000

Am I missing something?

What do I have to watch in these deals?

Some of these printing/copier companies seem a bit sharp???
