TT rackets

I have a short pimpled bat. But the handle is short and one of my friend said that the bat was for people who play with penhold grip. I use seemiller grip. My PT sir says that my bat is a good one. But I think for a replacement. Can you suggest me a good (low cost) bat with which I can spin almost all shots comfortably. I am a good spinner and need that bat to be good for spinning too.

Thanks in advance.
