Bingo, royesses, that what I wanted to know. So, I may stay with mini lathe. Just improve it a little bit. I have 30206 bearings, and if I remember correctly, they altogether wider something like 1.5 mm then original. Problem is, I do not know dimension of the spacer until I remove original bearings and get access to the spacer. Besides, I was told to replace the spacer with a metal one. But not sure which one was mentioned, that one, or other, which sits close to double nut on left side.
Edit: spacer in question is white one on picture 6 in http://www.arceurotrade.co.uk/machineguides/Mini-Lathe-Angular-Contact-Bearing-Change-Guide.pdf
But make a metallic one I think was on pic 3, black one. Same URL
I don't know if you can order from littlemachineshop.com will they ship to you?, but you could order the oem spacer from them and make it out of any material you'd like. Also you could take it apart first and measure what is in yours. Your bearings are each 1.25mm thicker than the original bearings. So you would need to cut the spacer 2.5mm. I've had mine apart numerous times and don't even need to remove the headstock from the lathe to replace the bearings. I do use a blind bearing puller to remove the bearing from the housing. LMS may actually give you the dimensions over the phone. Worth a try. I may put the 30206 bearings in mine if the angulars don't pan out. So far so good though. Also the reduction pulley kit claims a 65% increase in torque. I have uploaded the arc-euro roller bearing upgrade instructions in pdf. Don't know if they will help you or not.

If you have a c2 7x12 just the rear spacer needs .010 or 2.5 mm cut off the length according to LMS. From LMS:
This spacer goes on the spindle shaft behind the rear bearing.
This plastic spacer is 40 mm OD, 28 mm ID, and 32 mm long.
This is a tapered roller bearing that can be used to replace the spindle bearings on the mini lathe. It requires two of these bearings to update a mini lathe spindle.
These bearings are slightly wider than the standard bearings so the rear spacer must be shortened about 0.10" to use them.
