It is really hard for us to help you. When I didn't want to spend much money I bought machines for $700 and $800 dollars. You may think that is a fortune or not enough! Machines go all the way from really cheap - $99.00 to $10,000.
You got some good advice above.
After you have settled on a couple, use the internet to search for reviews on the machines.
Also, search this board. This question comes up at least a couple of times a week.
