We have 2004, 2002, 1140, 1120, 1230, 1220 phones.
2004 and 2002 take more desk space (wider than others).
1140 and 1120 are good but expensive.
1230 and 1220 can only show 9 digits of stored AutoDial numbers.
1230 (1220, 2002, 1120 as well) can only show one line of calling party's info at a time. You need to arrow up and down to see the all. You can choose to see the name or number first though. It is the tradeoff of its 20 programmable keys for 1230.
