I bought one from amazon in 2019 which is no longer available, but it was less than $20 and it has worked out fine for me. I use on occasion not everyday. It is 9x12 and plugs into a usb port on your computer. Works great, has adjustable brightness, and I can trace onto card stock as well as fabric, if that helps. I see that now they are about $21 and there are a couple that have a very high rating. Sometimes amazon will have one listed in the daily deals or maybe wait until they have a prime day and save a bit then. Either way, amazon does have a very generous return policy and if you don't like it, or it is not what you want, return it.
