The Fully adjustable desks are great, they have motorized models with memory settings so you can one-touch to switch between sitting and standing. The desks have 4 settings so you can easily save 2 people's sit and stand preferences too.
They also make a great series of monitor arms that will get your monitor up off your desk and give you more room to spread out papers/books.
