Centerline,
I have been using a HP2500C for about 5 years now. It has been an awesome printer. It has 3 trays and all of them will hold up to 13 x 19 paper (and lots of it to boot). I have it setup with 11 x 17 in one tray, and letter size in another. The 3rd tray is essentially a manual "use as needed" tray for special things (such as labels) since it only holds about 10-15 sheets. The printer automatically "knows" which tray to grab from depending on your printing size.
It cost us a little over $1000 new, but it has since been discontinued. The newer version of this is the HP2600C and it is priced somewhere in the $800-900 range.
When we bought it and I started using it, I was so impressed that I wanted to get one for home. But due to the expense, it never happened. However I just looked on eBay and found several good used ones for under $200. I may be getting one now.
I HIGHLY recommend one of these, even used!!! This thing has printed TONS and TONS of prints without even a maintenance call. It has never even had a hiccup, until just last week. I started getting errors on the display and would not print. So I took it in to our local authorized repair shop and they could find anything wrong with it. So I brought it back and its been working fine ever since. Guess it just needed a car ride.
One thing though! It is a rather large printer. It is NOT one of those printers that you will just sit on your desk next to your monitor. It measures about 27W x 14T x 30D (with the large size paper tray installed). I wasn't expecting it to be that big when it arrived several years ago.
