Keep in mind that in that area "tall" really isn't very -- a couple years ago, a development in Pentagon City had to get a variance for the height limit so it could go up to 22 stories.

In addition to the options listed by mhnadel, the new Silver Line opens up some possibilities in the Tysons Corner area; sites such as this should be helpful. Prices are in the range you're looking for, but height probably won't exceed 10-12 stories. Depending on where in "McLean" you're working, some of them might even be walking distance to work, barely.

Also, keep in mind that you could own a nice 1-2 BR home in the same area and pay well under $2500/mo in mortgage and taxes, but of course that requires having the down payment funds.

Full disclosure: I will soon be selling my 3BR in the area.
