When shopping for a drill press, a quick quality check is for quill play. Wind the quill all the way down, and move it side to side. If you can feel any play the fit is not so good. Sometimes the store will have a few units around and you can pick the one with least play.
 
Another thing you will want to check is whether the table is square to the quill axis. You can do this by finding a piece of 3/8" (or bigger - whatever will fit your chuck) KNOWN STRAIGHT round stock, chuck it, and use a square between it and the table to see if they are at 90 degrees. Check front to back as well as side to side, often imported machines are not square at all. Usually shims of thin stock / bean or drink tins can be used to correct front to back problems, and the table adjusted to correct side to side problems.
 
KNOWN STRAIGHT round stock is just round stock that doesn't show wobble or bends when checked on a surface plate or laminate countertop or piece of window glass. All these items are usually surprisingly flat.
 
Good luck.

And don't forget that SOME manufacturers have been know to increase the weight of their products by forgetting to clean the casting sand out before painting. - Don't arf lap spindles in quickly.

Thanks so much guys.
Picked up a few of the odd size drill bits today along with centre punch, an M2 tap (only one I did'nt already have) and a nice new set of files with soft touch handles.
All that is left now is the press, vice (going to stick with a horizontal to use free hand and on the drill press) and some nice green enamal

While you are checking things make sure the table is flat. Mine is not. It is raised to the centre. Again a good sraight edge should prove the point.
I'm hoping someone in the club will have a milling machine big enough to sort out the problem.
