How serious are you about woodturning? Remember: The lathe will most likely be the least of your overall expendatures if you get serious.
If you're just looking to turn the occasional pen, bottle stopper, spindle, or small bowl, there are a number of options. The Ricon and Jet both have their following, and from what I have read, are fine machines. If your budget is extremely limited, however, you may want to consider the Wilton, available from Amazon.com for about $99. This is the unit which I acquired. It has about a 7.5" swing, about a 13" or so spindle capacity, and sports a 2/5hp variable speed motor, 500-3200 rpm. Not much, I know, but it is a cheap and easy way to get into the hobby.
You will also need some chisels and something with which to sharpen your chisels. If you do not already have these, I would suggest the HSS set available from Harbor Freight. It's less than $40, and makes for great practice in sharpening and in turning. It is geared towards spindle turning, however, so you may want to consider a bowl gouge and a couple of shaped scrapers.
Unless you get the Jet deal from Woodcraft, your lathe will most likely not come with a chuck (the Woodcraft deal, if still extant, comes with a Nova chuck, if I remember correctly). Scroll and/or spigot chucks can be invaluable in turning hollowed items. By themselves, these items can range from $50 at the low end to better than $200+ at the high end. Most have the capability to swap out jaws, but of course these are also an added expense.
This is what I started with, in order of purchase:
Chisels and Bench Grinder
Lathe
Finishing materials
Chuck
Vernier calipers
Bowl gouge, double-ended calipers, anchorseal
small votive candle (for an oil/wax finish---already had the baby oil)
I wish you the best of luck in your search, and enjoy the hobby!
