Ok im after some advice on product please.
Ages ago steve timepsycle did some casting for me and I think im ready to jump in and give it a go.
Just need some help in what product is good to start with. I searched on ebay and typed in resin and got a whole host of what nots and I have no idea what one is the right one I should be using.

I would go for a 2 part fast cast polyurathene resin.. just mix equal parts and pour.. you can also add colouring pigments to if you want a specific colour.. once dry its dead easy to work with, a bit like styrene plastic almost..

 

Ive used this stuff with good results: http://www.ebay.co.uk/itm/Fast-Cast-Polyurethane-Liquid-Plastic-Casting-Resin-Kit-1kg-960-ml-/281205901265?pt=UK_Crafts_DrawingSupplies_EH&var=&hash=item41792d87d1

castings the easy bit.. making the moulds are a bit trickier but not too bad if you put a bit of thought in first..

I think for the most part I will use the two part miliput for the molds and then the resin for the copies.

not sure if milliput will be suitable, depends on the shape your casting, if its a simple shape with no undercuts it should be ok but I think you are better going with rubber instead.. a little costlier but worth it in the long run..

 

This stuff works well if you want to try a small amount http://www.ebay.co.uk/itm/RTV-NEW-Silicone-Rubber-275g-Kit-Hardness-A40-/251079609424?pt=UK_Crafts_Ceramic_PotteryMaking_SM&hash=item3a7582cc50

 

better buying it in larger quantities though as it works out cheaper but its a good starter one.. dries semi clear though so adding a colouring agent helps to see the detail in your moulds better

Rule of thumb is soft master, hard mould.... hard master, soft mould. There are exceptions, of course, but tread carefully or you may lose both mould and master if they become locked, or worse still, stuck together.
