Hi sorry only just saw your questions. Hope I can help. Firstly my microscope is a york one. Check them out on line or go into a york store, there is one in melb cbd, not sure what state you are in. The cheap ones were really rubbish and you can't see anything, basically I got the one that goes up to 400x magnification, don't need the colour wheel makes no difference, but you will need to buy some slides to put your sample on and somethings called cover slips, they are small very thin pieces of glass that sit ontop of the sample so that when you magnify your sample the microscope doesn't dip into it(you have to get very close to the sample to magnify), the microscope cost $150 i think. In as far as the incubator, you cannot buy cheap ones here, but it is so easy to make your own. I bought an esky (from coles of all places) it is basically just a polystyrene foam box ($16), I got a lamp that the on off switch could be hung on the outside of the esky (basically a night light), and then I got a cooking thermometer that could show both farenheit and centigrade and poked that into the side of the esky. I also put a rectangle piece of polystyrene into the esky to hold the sample at 45 degree angle. I found that the esky takes time to heat up, so I put 2 fans either side to blow warm air onto it (which I then switch off when the incubator has reached the correct temperature. In as far as test tubes I bought plastic ones online from a kids science website, cant remember which one, but it is in oz, they came in a set of 10, I then sawed off the top as they were too long too collect the sample easily with needless syringes. Needless syringes you can buy from your local chemist - terumo are the best, they have a really smooth action so as not to harm the spermy tales. If you need any other help please let me know I have tried test runs everyday for nearly 2 weeks and have got this whole incubation thing down pat.
