My Medion graphics tablet that I got really cheap off ebay a few years ago has been on its last legs for a while and was not working properly on my Macbook (the middle was responding as the top), and it doesn't work at all on my Snow Leopard Macbook Pro. Anyway since then my pen has broken so it won't even work on my Windows netbook so I figured it was time to replace it. It is an A4 graphics tablet but I have heard that sometimes smaller ones work better. Does anyone have a recommendation for a graphics tablet that preferably works on Mac and Windows? If you can recc one under £70 that would be a huge bonus, under £50 would be even better (I paid £30 for my Medion A4 tablet that was a rebranded Aiptek). Thank you.
