There is an alternative. The exact same music is on the bonus CD that comes with the Sega Saturn Thunder Force V Special Pack. There are four copies of this game on eBay right now, with the lowest starting at $80.
And the first eight tracks are all on previous Technosoft albums. I think the first four are on Technosoft Vol. 6, and the next four are on Technosoft Vol. 7.
Edit: Here is the VGMDB entry for this bonus CD:
