Alternatives to proxmark 3?

I was wondering if there was an arduino compatible 125 khz read/writer under $20 that works with a t5577 chip?

Reader yes. Writer no project that I have come across yet if you find one please post it.
With a $ 20 budget you could just modify a blue cloner

But do modify the antenna. And do some research on it I know there has been probs with this one in the past and people accidently locking there chips
