I see that no one has responded to this post in two weeks.
Tell ya what, take off the current handle and measure the drive-shaft hole, length-wise. If it is 8mm long, then almost any Daiwa or Garcia power handle will fit. If its 7mm, then the current power handle from the regular old 400BSV will fit it perfectly.
I know the 300 and 400te reels take the 8mm handles, but I can't speak to the 200te - because I've never had one apart. It might well have either size handle on it.
