I agree with that. The budget version needs probably 2-3 Helms and then something else in the mana department to help feed the combo (Desperate Ritual, Simian Spirit Guide.) It's important to note that Desperate Ritual is actually Dark Ritual with a Medallion/Helm. The budget version will likely lean on Reforge/HUF in a greater way as well.

If nothing else happens, the real breakthroughs for mono-red storm seems to be these:

1) Mana reducers are good, even in legacy
2) Act on Impulse can be a powerful draw spell, especially with LED
3) Past in Flames can carry a deck
4) Red rituals can be as explosive as black rituals
5) Newer cards are pushing the limits for power level to enable fringe decks (Hazoret's Undying Fury)
