i don't know what everyone else is talking about: you can get an excellent head unit for around 250. it just depends on how much you will be expanding your system later on. if you don't need three preouts (an extra one for sub control) then i highly suggest getting the kenwood eXcelon x615 head unit from crutchfield. it is last years model and when combined w/a 25 dollar coupon it can be had for 225. or if you are planning on getting a sub later and want a third preout get the kenwood eXcelon X617 (this years model). it is 275 w/copoun at crutchfield. this model is basically the same as last years but adds a third preout and looks a tad cooler. i must say im a bit biased (see my sig

), but i have nothing but praise for my kenwood hu so far. Id have to say that the only downside with the unit is that it lacks a rotary volume knob, but kenwood compensates for this with an attenuator button (basically its a big name for "mute").
if you don't like kenwood, the nakamichi cd45z is a very good unit. also the alpine series is nice. however i got my kenwood b/c it reads cdr's like nobodys business!!
im in the bay area so email me at vtite@hotmail.com if you need further assistance.
