For learning, the cheapest machine is a Brother from Walmart. Now, be careful. There is not much "learning" to do. The machine does all the work and you just change the thread and watch it do all the work, so you outgrow it very quick and find yourself wishing you had gotten something bigger very quickly. The cheapest ones can only do designs smaller than 4 x 4 and there are so many designs available that are bigger than that! That is, if I read your post correctly and what you want is an embroidery machine.
