You may be able to find the Ikea Jerker on craigslist or other classifieds. I got mine from a college student for relatively cheap, I think around $40 or $60. It works great as a standing desk but you don't have any motorized mechanism to lower or lift the desk. This is probably a good thing if you are trying to stand but an alternative solution is getting a high-rise stool/seat. I alternate between standing and sitting now.

I just got one of these[1] and I'm loving it. My wife laughed hard when I ordered it, but after testing it out she was practically cooing.

It's $100 and it's almost perfect - the one thing I may do is add an angled footrest. But I'm not in a big rush.
