[Suggestion] deep mining drills to workshop

I like to see deep mining drills for the workshop on different tiers and costs like TIER 1: a cheep one there is at biofuel deep drill powered by biofuel (like the biofuel one you can craft) TIER 2: a bit more expensive deep mining drill powered by electricity ore IC-001 P.P.S (like the electric one you can craft) TIER 3: much more expensive deep mining drill powered by IC-001 P.P.S (+50% deep mining drill speed) TIER 4: very to extremely expensive deep mining drill powered by internal power source and are is (+50% deep mining drill speed) IC-001 P.P.S (IC-001 Prototype. Power. Source) so we got something to work for
