150 is a great price on the Blue Onyx. Expect to spend another 300 on restoration with correct parts. If you drill holes in them for those damnable pipe mounts...... The drumgods will visit you with nightmares.
I would never drill holes. I meant hardware as in cymbal stands, floor tom feet and bass drum feet (if they would fit?), snare stand, etc. And then I'd try to find the correct Swiv-o-matic? tom mounts. I've read the blue onyx pearl is a very rare color, not to mention it looks awesome.
