Hello,
I might suggest to check with HP to see if these switches have not been end of life / end of sale.
We have some materials here and there, and if you follow this next link, the top link will take you to the fixed configuration switches versus the competition:

Are you in touch with your sales or SE? Many times the account teams can help you win. We always want to win ;-)
If you need a L2 switch, click on:

If you need a L3 switch, click on:
