I have heard more than one person say that you can figure on spending as much or more than the machine on tooling and that is probably true in the long term. Most of those machines seem to come with a drill chuck, so you would need a vice and probably some collets. Hopefully some one with more knowledge than I have will speak up but I think you will want to use collets to hold your end mills and cutters. The end mills and cutters will depend on what you are working on. Check for a machinery dealer in your area a lot of them will have used stuff so you may be able to pick up a small vice and other odds a little cheaper, but I'd avoid used cutting tools unless they resharpen and packaged them.
A few sources to get started:
Travers Tool Co.
www.travers.com I have never dealt with them but we get their catalog at work and they send out monthly sales fliers to customers.
DoAll Inc.
www.doall.com DoAll seems to have stores in a lot of towns, I have bought a few things from them. Their local store doesn't have everything in the catalog but, has quite a bit of used stuff.
Enco
www.use-enco.com They send out an e-mail sale flier monthly
MSC
www.mscdirect.com I have buy quite a bit from MSC, fast shipping and I seem to get at least 2 sales fliers a month one for metal working and one for MRO supplies.
Rutland Tool
www.rutlandtool.com I have bought a lot of stuff from them over the years with no problems, most orders are shipped the day they are received and within reason (I don?t think they do this for really heavy orders) are shipped UPS blue for the UPS ground rate.
Micro-Mark
www.micromark.com Sort of a model makers catalog but they have lots of stuff for the small lathe and milling machine including kits to convert them to true inch feed screws and hand wheels.
I don't get anything from any of these companies for the plug; I am either a happy customer or have noticed they offer something that may be useful in this case.
http://www.mini-lathe.com and
http://www.cartertools.com Both have a lot of information on use and modifications to make the small lathe and mills perform better and a ton of links, it should keep you busy for a few hours.
