What non-prime weapons should I get?

[Jesse]

I was just wondering what non-prime weapons are a must have? I have all the research in my dojo completed and I have a ton of credits that I have no use for (I've been using it mainly on upgrading mods) so I was just wondering, what weapons are best?

Bonus question: What non-prime warframes should I make as well? So far I have Saryn, Rhino, Ember, Excalibur, Mag, and Nyx.

Some of my personal favorites are:

Primary:

Kohm
Attica
Ignis (though it needs a lot of work to shine)
Amprex
Dread
Hek
Grinlok

Secondary:

Angstrum
Gammacor
Marelok
Akbolto
Seer (It's actually kinda crappy but something about killing Grineer with Vor's own gun is so satisfying.)
Kunai (Not very good but makes you feel like a ninja)


Melee:
Amphis
Atterax
Glaive
Jat Kittag
Tipedo
Nikana/Dragon Nikana

Had a lot of fun with:

Pimaries:
Sobek
Hek
Supra (though most don't like this)
Grakata and vairents
Ogris (a little outclassed right now, but still solid)
Opticor
Latron
Ignis (not gonna carry you later, but still fun for quick missions)

Secondary:
Stug (wierd but very potent)
Lex varients (prime is worth your while)
Nukor
Atomos
Secura Dual Cestra (might need Steady Hands if not used to high recoil automatics)
Acrid

Melee:
Halikar (surprisingly fun, explosion is currently glitched so not all glaive builds work)
Jat Kattig
Ankyros (standard has different stance than prime, seismic palm is a lot of fun for me. There are more powerful options, though)
Jaw Sword (a little weak without Crimson Dervish, and rare, but still shines for me)
Amphis
Kronen

The weapon you will enjoy the most

[WalterREQUiEM]

Primary:
Tonkor
Dread
Hek **
Tigris *
Vectis (better than the prime)
Opticor
Amprex
Sybaris
Penta *

Secondary:
Akmagnus
Despair
Furis (with Winds of Purity)
Kulstar
Twin Grakatas
Kohmak
Atomos
Brakk
Marelok *

Melee:
Dual Cleavers *
Ack and Brunt
Tipedo
Ripkas
Jat Kittag

Warframes:
Pretty much everyone is good, but I'd say avoid Trinity FOR NOW because the next prime warframe may be Trinity and it would be better to get the prime.

Everything I've mentioned here is more or less end-game with a bit of forma. Anything with a * next to it means it has a unique version that's worth getting over the regular one if you can, but the Vaykor Hek is more of a sidegrade to the regular one. I'm also not mentioning unique versions of weapons that are really good compared to their crappy normal counterparts, like the Prisma Gorgon and Prisma Grakata, the Rakta Cernos, the Synoid Simulor, ect cetera, because those are essentially prime weapons.
