There are other tweeters that will work, but some of them get pretty pricey. The DX25 sounds great for the price, in my opinion. It's a good match for the Alpha 8/10.
I wish I could remember some of the others, but it's been a while since I checked. Seems like there's a Monacor and a Vifa or two that will work, probably others too.
One thing about the soft dome tweeters, they tend to be pretty easy to work with provided they'll handle the low end without too much THD and IMD. Match the sensitivity and get a tweeter that is smooth from ~1kHz up and you'll probably have a winner - again, provided it can handle the low end without distortion.
