KerbalX

1.9 Tons to LKO
1/3 return money rate (Excluding cargo)
2 probe intersage cores (can obtain minmus easily)
Easy to fly!

Costs are actually lower than 20K. -pretty neat.

For Those who aren’t as good:
-Take it to an ‘Almost-Orbit,’ then use the Probe interstage to achieve orbit.
-Switch craft (using the ‘]’ key)
-Reenter the Core stage (Orient Retrograde)

NOTE: This SSTO can release an engine (the jet one) to get further, faster. You will need to detach this engine manually in flight to do so.

This SSTO is NOT a pure one, in that it doesn’t perfectly achieve orbit, but makes the next stage have an easy little puff to get there.
