How many own more than one lathe?
http://www.woodcentral.com/cgi-bin/turning.pl?frames;read=42391
The responses to the latter are overwhelming. I have only one lathe but lately really wish I had a smaller one for collars, or even a 2nd big one for a dedicated hollowing setup.
Not too many table legs exceed 30", but be careful with whatever you buy because sometimes the advertised bed length doesn't take into account the tailstock requirements.
In the reviews section I have a write up on my first lathe - a Delta 1440. Please check it out before buying a lathe, it might help you realize some important things to keep in mind when purchasing a lathe.
