Smooth horizontal and vertical camera movement
Unfortunately, there aren't really cheap options to do this.  You can approximate it using a crane or a stabilization rig (like a SteadiCam Jr), but both of those is still going to cost you hundreds of dollars.  

For horizontal movement, the cheapest option is probably to use a more basic track and roll it by hand.  You can use a motion control unit to get smoother motion, but a motion control unit itself is going to be over a grand normally.  

For pure vertical, you need something called a camera pedestal.  Unfortunately, this is probably the most complex movement to perform in a controlled manner, so there simply are no cheap options.  There are some DIY approaches out there, but you're looking at expensive hardware if you want to do a pure vertical movement with good control.  (The cheapest commercial pedestal I know of is over a grand.)

That is just the way the market is for being able to do advanced moves.  They are all specialized, limited use devices and the cost rapidly multiplies with the weight of the camera.  That's why rigging costs so much, because the market is so limited and specialized.  It requires careful design, tight tolerances and a very limited market, that all adds up to big costs to the consumer.
