if you can live with the limitation, a laserjet is definitely the way to go. prices have really become reasonable and they are well worth it and most can handle a decent load.
for what you are asking you need a simple all in one. i like to stick with hp but it's tough to use aftermarket inks with them. do you have an ipad by any chance? id make sure to get an all in one that supports air print. you can find some models for about $80 that do all that you say
