I don’t really think you will get anything decent for that sort of money. I paid £700 for my Myford ML7 off eBay a couple of years ago which came with a stand. You might be lucky and get one a bit cheaper without the pukka stand which will be fine if you mount it on a sturdy bench.
There are a lot of Chinese made lathes around from dealers like Amadeal (http://amadeal.co.uk/index.html) and a lot of those tend to be clones from one or two factories in China. They look like good value but the quality of them is pretty poor even though they have improved over the last few years.
I was in the market for a lathe a few years back so went to the Model Engineering Exhibition to look them over. All the Chinese clones were obviously of inferior quality so I decided to hold out for a second-hand Myford. If you want to go smaller then the Taig/Peatol lathe is very nice and second-hand ones do appear on eBay from time to time.
There are quite a few websites around dealing with small/hobby lathes with good advice such as this one http://www.lathes.co.uk/page2.html
Hope that helps.
