Are there any computer controlled trackers for a small antenna like an arrow out there? I'm in the market for one.
Thanks!

Lee,
If you are willing to do a little construction, WA8SME has a very nice design which appeared in QST, called WRAPS. Completely shameless plug! You can order the key circuit board, bare, and programmed PIC chip on the AMSAT Store:

It is $30 plus modest shipping. You can find a link to a download of the article. I haven't built one myself, but construction is straight forward and doesn't require any exotic tools or skills.
Over the years there have been a few other similar controllers, but none that I am aware of which are currently available assembled. Another approach some have used is to use Yaesu rotators with an inverter to power them. That would not be a cost effective way new, but you sometimes find them very cheaply at hamfests.

It seems the construction article is available to ARRL members only. Or is it legitimately available from another source?
You can sign up as a guest to get access for a short time (days? weeks?); you can also write directly to WA8SME (at the obvious arrl.net address). And if you spend the $33 to get the board from the Amsat store, you get all the construction info on DVD.

Gus,
It is available for downlink on the AMSAT Store. It is part of the description.

Just a note that the pdf available on the Amsat web site is the QST article. I don't think there is enough information there actually to build the WRAPS, although you will get the general idea. The Amsat store also has a link to QST-in-depth, where you find the construction details on the member's pages, but you still need to log in, either as a member or a guest.

Thanks! I didn't realize that guest-login was possible.
I just went to get the link to give you in order to register as a guest, and I found this:
(As a guest...) For a 90-day trial period you will be able to:
- Customize your home page to see local ham radio events, clubs and news - Receive E-Newsletters on topics you select - Have The ARRL Letter delivered to your inbox - Find and download Product Reviews from 1980 on. - Search for articles in the ARRL Periodicals Archive (article downloads available to members only)
Notice the last bullet. I had not noticed this before; it looks you might not be able to download the extra info as a guest.
Sorry about misleading anyone, although it might be worth trying. And the store description does claim that the info to build it is on the CD that ships with the circuit board.
